Excellent Product for XDA 2 Speaker Mount 4 tomtom sat nav

I came across this product and had to order one for my tomtom kit, it is the loudest speaker moutn I have ever heard, and the XDA 2 fits in the mount perfectly:
http://www.pdamods.com/products.asp?cat=78
I used to have a ipaq 1910 and the speaker on that was rubbish, then upgraded to an XDA 2 and thought it was better than the 1910 but could not hear the voice directions if the radio was loud, however this mount is seriously amazing, it has its own built in amplifier with full volume control.

I have got this holder for the car, unfortunately the TomTom GPS receiver has a RJ11 connector and the holder has a mini USB port, so therefore i can not use it.
It came with a PS2 to mini USB connector and thats it.
Very sad if you ask me
I'm now waiting for a lead connector from TomTom RJ11 to Mini USB

Sorry to hear that they may have made a mistake cos I chose tomtom cable and they sent me the RJ11 cable - believe me when you get the right cable you will love this device !!

On ebay is sold a little rechargeable device called car baby, it clips over the speaker and then you get the audio from the xda or any other device through your car speakers.

Arkon PDA Mount
Hi guys,
I'll let you know my experience with the Arkon car mount kit.
First what I have?
1) O2 XDAII
2) Arkon car mount kit for Vent and Windshield mount.
3) Arkon cables for XDAII
4) Emtac CRUXII/BTGPS
What you gain?
1) A complete car kit that charge both devices (XDA and BT Gps)
2) A handsfree car kit with a good speaker
3) A handsfree Navigation system
Hope this helps a choice.

All these powered mounts are great (i've got the Arkon PDA Mount) except that they all pick up the background radio signels that the phone transmits when it is active or syncing with the network and that's really annoying if you're driving along trying to listen to anything else.

I've had the same problem as you jashry but I've found a little S.P. (Service pack) to that.
Just turn the 3,5 mm cable so that it touches the Arkon device on the backside. And you'll hear less noise due to GSM signal.
Hope it helps!

Arkon 700 car mount for XDA2
I called a well known supplier of kit based in Manchester and asked for a car mount for the XDA2, to run with (and charge) a Bluetooth Tom Tom headset.
The first set came without an audio lead - so rendered the XDA2 useless for receiving calls.
I called and was rudely told of the company's arcane returns policy which made me see red (working in the legal profession) as the kit was clearly defective. To save time, I bought another one subject to some concessions re postage and return of the original etc.
The second kit arrived - complete with a 3.5mm audio lead. The XDA2, which I specified, has a (standard for mobile phones) 2.5mm audio socket. So, it is still useless.
Tried it with a jack adapter (3.5 to 2.5mm) - sound is barely audible, even with everything turned up and "loud' selected on the Ultra Profiler. So, both are now going back with a terse note regarding the Sale of Goods Act.
Can anyone recommend a good car kit (and where to get one from, ideally quickly). Basically, I need something loud and reliable, that will charge a TomTom bluetooth GPS. Ideally, I would like something that can be vent mounted (neater, less 'shake') tha can be hard wired (neater).
I am afraid that finding a jack adapter was at the limit of my technical abilities - suggesting that I splice this and patch in that is akin to suggesting that I learn to fly or communicate by ESP. I wish...
Thanks

PDAMOD Speaker mount for Qtek
Bought one of these mounts that Jashry recommended, but I'm having all kinds of problems with it!
To use the amplifierfacility I have to use the audiosocket in the corner of the Qtek, and they do indeed supply a small cable for that.
But when this cable is mounted, the Qtek barely touches the bottomsocket of the mount, and the connection is lousy!
Actually I HAVE heard the voice, because I can "rock" the Qtek to the side a little, and then I can test the TOMTOM voice, and it sounds great, problem is this prohibits the connection to the GPS, so at the moment it is useless.
On their homepage I can find pics of a Qtek in the mount, but without the little cable in the corner....!
Wonder if anyone uses this device, and if they have had the same problems and maybe somehow solved them?

Sorry I'm a bit late on this thread, but have you tried using an external antenna lead on your device? This should direct all of that radiation where it belongs.
I have to add that I haven't chosen my amplifier cradle yet because of this issue, but I am eager to know whether the antenna theory does work.

I too tried the mount recommended (after the Arkons which went back) and the loudest sound I have ever heard is interference from the radio signal of the 'phone.
Anyone want one? At the moment it is just an overpriced charging cradle.

I now have a 'Silver Shield' mount, and yes it does sqawk when the phone transitter is operative. However, it also does that when I hold it near my nokia, but not when the nokia is in its car-kit. I should be receiving an external antenna tomorrow, so I'll let you know whether the theory works in practise. In the meantime Dr. Fresh, I'll take any unwanted goods!

I tried the Arkon mount, it landed somewhere near the service station at Bristol on the M5 when I launched it out the window, interference was so loud, it should have been returned to the designer and inserted up his ass....sideways.

It works!!!!
Just got my external antenna and adaptor; plugged it into the XDAII, inserted this into the amplified mount and hey-presto, you can hardly hear the interference, whilst the audio signal is strong enough that you could leave the whole lot at home and hear it on a trip to France! (Well, almost!)
My only problem now is that the Antenna adaptor is a bit bulky, sticking out of the back (about 11mm or so), which makes it a little lop-sided in the holder. I now have to take a look at modifying the mount to fit the connector in. Will let you know how I get on

Inspecta. I am interested to know if using an external antenna fixed the problem. I think it will probably make it worse, it is direct rf breakthrough from the phones radio causing the problem and I think the antenna lead is just another place for it to splash its unwanted interference over.

Interference
Hiya Cruisin,
absolutely, it is the external antenna which rectifies the problem.
When using the internal antenna, all of the r.f. energy is in close proximity to the speaker and amplifier. By using an external antenna, you have the same amount of energy, but it is radiated from the antenna located on (in this case) the windscreen. Energy is radiated in all 3 planes, so the interference reduces by the CUBE of the distance, therefore, by doubling the distance from the speaker/amplifier, the amount of interference reduces by eight times. You can verify this effect by placing any mobile up to your car radio; it will eventually pick up the noise, no matter how good the radio.
........ sorry about going off on one! Yes it does work; I removed the external antenna, and the set-up went back to its bad old ways, replaced it and everything is great!
(Now got to get some shares in external antennas!)

And now I will admit my stupidity by telling you I was pretty stoned when I wrote that reply and for some reason i thought you were referring to an external gps antenna, now I cant blame the dope so i will accept all responsibility, thanks for the lowdown on the rf.

or you couyld get a holux like received this morning just tried it and its great amplified speaker and built in gps receiver worked with my xda2 no problem

Must have missed something here.
I've got an arkon powered mount CM532 with built in speaker and gps connection but the voice prompts from the nav software only come thru the internal speaker on my XDA2. I can't get them thru the mounts speaker.
Any suggestions?

Did you get a cable to plug into the handsfree socket and into the amplified mount? You need this for all of the mounts that I looked at. If you ordered the mount specifically for the XDA, you should have received a cable to go with it.

Exec - HTC Universal External Antenna

:?: I need a cable to connect to the phone antenna ports on the device - the port is smaller than the ones to be found on some mobiles (such as my old trusty Nokia 6310i) and I need to find out what type of connector is needed.
Does anyone know where a cable can be obtained or what type of connector is needed ?

I need a connector also
It took me weeks to find the special connector for my XDAII. Now I'm in the same boat for the Universal (JASJAR). I've been searching the net for a while to no avail, but hopefully I find one soon and let us know. :?

Sorry just too lazy to go through the manual so decided to ask the enlightened friends on this forum. I want to know if the antenna socket provided at the back of the Universal is for GSM signals. The GSM signal in my home room is too weak so I thought that attaching an external antenna would be beneficial to the strength of the GSM signal. But obviously even if it is so attaching an antenna would be possible only once we have found a suitable connector.
Kind Regards

I mounted an antenna outside my house
For the last 2 years (with my XDAII) I've used an antenna I ran through my outside brickwall and mounted outside my house. It helped the phone go from NO reception to a pretty good signal. I still have the cable running to my office/desk and all I need now is the connector. It has to be out there somewhere. I ended up buying my previous connector from http://digikey.com, but it ended up costing $30 ... but it was worth it. I'll do more digging today and see if I can find out more.
Oh and by the way, I was using GSM on my XDAII and the manual for the Universal says the connector (closest to the center or USB) is for GSM/GPRS.

Anyone find out what adapter fits the jasjar? My adapter for the pda2k does not fit.

I'm still looking
I've sent emails to PDAGold, HTC in Taiwan and i-Mate to not avail. I'm going to keep on looking. Obviously someone has to know.

Some progress - I've found out the connector type
The connector on the phone is a Amphenol MHC-H196.
I've posted a pdf with all the specifications of the connector on the circuit board ... http://wiki.xda-developers.com/uploads/MHCH196.pdf
Now it's just a matter of finding the correct adapter.

Well I gave up trying to find one and made my own
After spending many hours looking and getting an official "not available" from digikey.com (who I got my XDAII adapter from) and imate techsupport ... I decided to make my own. I haven't been able to test it with my Jasjar yet, though, since it's still being repaired at Topp Solutions in Miami.
I ended up using 26 gage solid wire (which is .4mm diameter) and a .062 inch (1.6mm) diameter female pin connector. This is smaller than the diameter of the connector on the phone, which is actually 1.82mm. Although, I expect it to expand slightly (permanently) when it's slid over the connector on the phone. Obviously, it's very crude for now. I just want to see if it works then I might make a prettier one. I included some pictures for fun. By the way this cost me about $9 in material (which I can use for other projects) vs. $35 for the last adapter I bought for my XDAII through Digikey.

Did you see the interesting comments made by WilsonsElectronics. HTC really stuffed up with this one.
Is there any news on this matter.
At the moment I have sent an information pack to www.pasternack.com and I am currently waiting for a response. These people do customised products. See under technical support. I will keep you friends informed.
http://www.pasternack.com/ContactUs/ContactInformation.asp

I am after an adapter to get a signal booster... www.digitalantenna.com
I talked to them about three products. there email follows
Description Part Number List Price
60dB gain repeater system 4KSBR-50U $699.95
40dB gain repeater system 4KMR-30U $559.95
Direct Connect Amplifier DA4000 $299.95
DA4000:
The DA4000 amplifier must be purchased with an antenna and cell adapter cable and is a direct-connect system. The antenna is placed on the roof and connects to the inside amplifier which with the correct adapter would then connect to the cellular device. We have many adapters for different phones and air cards. If we do not have the adapter for your type of phone or air card the other option is a wireless repeater. However the direct-connect amplifier can provide higher performance because you are directly connected to it. Please use the link at the bottom of this email to download our 2006 on-line catalog. On page 28/29 is our Cell Adapter Cables which lists the adapters per make/model of cellular phone or PC card.
Description Part Number List Price
Direct Connect Amp. DA4000 $299.95
9dB cell antenna 288-PW $129.95
Cable 340-50NM $79.95
Adapter Cable pg 28/29 $19.95
4KSBR-50U:
The 4KSBR-50U system comes with an external antenna, 50' cable, amplifier/repeater, power supply and an internal antenna. So the external antenna can be installed on the roof with the cable going to the amplifier/repeater inside the house. The internal antenna is also plugged into the amplifier/repeater and is installed inside the house. There must be 40' separation and a wall/roof/bulkhead structure between inside and outside antennas.
With a good cellular signal outside the house the 4KSBR-50U system can reach as far as 40 feet from the internal antenna. Generally the SBR can penetrate 1 or 2 inside walls only and each wall will reduce the 40 feet coverage. Also keep in mind the weaker the outside signal the closer you will need to be to the inside antenna. The 4KSBR-50U system must have a signal that is at or greater than -90db to be able to amplify/repeat it.
4KMR-30U:
The 4KMR-30U, 40dB gain dual band cellular repeater system, comes with an external antenna, 30' cable, amplifier/repeater, power supply and an internal antenna. So the external antenna can be installed on the roof with the cable going to the amplifier/repeater inside the house. The internal antenna is also plugged into the amplifier/repeater and is installed inside the house. There must be 20' separation and a wall/roof/bulkhead structure between inside and outside antennas.
With a good cellular signal outside the house the 4KMR-30U system can reach as far as approximately 18 feet from the internal antenna but will not penetrate walls. Also keep in mind the weaker the outside signal the closer you will need to be to the inside antenna. The 4KMR-30U system must have a signal that is at or greater than -90db to be able to amplify/repeat it.

More detail...at : http://www.boatersphone.com/Adapters.asp
Its the Nokia 359914 Multi Manufacture Cell Phone adpater, You stick a velco thing on your phone next to the internal adapter, and slide the nokia adapter into it. This is NOT a direct plug in into the External GSM jack of the HTC Universal device ( ie Jas Jar ). But looks like our only safe option. Not sure how the velcro thing goes on the device, the Jas Jar has a plastic back ( over the battery )???
Works on these networks, the site says : 900MHz/1800MHz/1900MHz/2100MHz networks
..."This is an extremely effective new kind of adapter, it works on a similar rinciple to the clip-on adapter, with the exception that it is tuned to work on more frequencies. We have tested it on all UK frequencies including 3G, and we know it works on the American 1900MHz band as well! This adapter was originally designed to work on Nokias but we have successfully used it on other makes of phones, making this a (hopefully!) truly universal adapter. It will work on 'candy-bar' style phones which have an internal antenna.
This adapter is two-piece, one piece is a velcro pad which has sticky-back plastic on it, and sticks onto the back of the phone over the internal antenna. The second piece is the adapter itself, which has velcro over the inductive plate, so it can be easily removed, and has a lead so it can be connected to an external antenna. '...

Where did you get the Information that it's a velcro adaptor?
reading the Page it says:
Plug-In Adaptor for O2 XDA Exec
More details about plug-in adaptor in general:
This kind adapter is called a plug-in adapter, for the simple reason that what it does is plug straight into the port on the back of the phone, and provides a cable connection to the antenna.
The plug-in adapter is preferred to the clip-on adpter, as it works on any mobile network.

I wrote them an email i'll keep you informed.

If you can get a plug in one then fine, but further down the page is where I get my info from. I highlighted in bold, just in case you cant see good.(Ha).
I'll bet the Jas Jar gets allocated the valcro one. As my experience is that its very difficult to find a plug one for the Jas Jar /O2 Exec.

Although I learly can read your bold text and being able to find this on on the page i really have no clue where you find the connection between the velco apdator and the O2 XDA Exec since it's marked with plug-in adaptor. Well we will see.

My apologies, yes "Plug-in Adapters", for "XDA, XDA II, XDA IIs, XDA Exec "..
BUT be carefull, the GSM external jack is very weak as per Wilson Electronic comments. Post me any confirmations of the plug in adapter working.

'Universal' adapters that apparently plug in
Their News page has a paragraph that describes a new adapter for various flavours of the Universal (although calling it Wizard to add to the confusion!) and warns against plugging in incompatible adapters. The adapters page lists the HTC devices under 'Plug-In' not 'Clip-on'. So that's why I posted.
I sent an Email after posting here, but it sounds like they are a small outfit so be patient!
Be careful with making adapters for transmitting antennae. For receiving antennae you can get away with almost anything, but for a transmitter a bad match on a connector will create reflections and emissions; it might even damage the transmitter (don't know if that's a problem here). If you don't see a clear increase on the reception bars with a well placed antenna, the adapter may be sending all the power straight back, doubling the voltage at the transmitter. Make sure everything is matched to 50R.

Reply from 'Boatersphone'
Can you do an adaptor from the obscure Amphenol MHCH196 socket on the HTC Universal Windows PDA phone? (XDA Exec, MDA Pro etc.). Presumably the other end is an FME f connector for the 'standard' phone antennas. Or alternatively the other end is a portable (non-mounted) antenna on 1800/2100MHz.
Many thanks

Hello,
Yes we have an adapter to connect the HTC Universal to one of our antennae and you are correct about the FME F connection. We don't supply an adapter direct to an antennae, only in a two-part system via an FME connection, to allow for changing of either part.
If you require a portable antenna we have a 3G/Multiband antenna with a magnetic base (on 850/900/1800/1900/2100MHz frequencies) or we have a T-bar window antenna, which is 3G/Triband, although this doesn't produce as good results as the magnetic antenna.

Benq E72 USB to 3.5mm audio adaptor

Hi Guys,
I have just got the fantastic little E72 and it is great in almost every way. I want to be able to use my Shure headset with it so I need the adaptor that everyone else wants to find it seems. I have a HTC adaptor but it will not fit into the socket. The socket on my E72 has 5 pin holes and both sides of the interface are curved. The HTC adaptor has one curved side and a straight side so it will not fit in. The E72 does use the usb connection for its headset and audio output but when I did find a Samsung adaptor with both sides curved that did fit into the phone socket it still outputted the music to the external speaker so I am at a loss. There are, therefore, different types of mini usb connectors. Can someone tell me the exact spec of this one fitted to the E72 and possibly where I might get an adaptor that will work??
Much appreciate the help with this.

usb cant be changed to 3.5mm or any type of audio
the reason the htc one dont work is the same reason it dont fit
it have extre connectors which carry analog audio
normal miniusb is a serial digital interface which dont carry analog audio
and usb headsets for pc are really external audiocards which make the serial digital data to analog audio
and that require the ability to usbHost which few pda's support

Many thanks for the explanation. However, my phone came with a stereo headset with mic. I currently use this for listening to music but the quality is not good. Does this not mean then that I should be able to get analogue signal from it??
Please forgive my ignorance; I am learning!!

it all comes down to where you connect your headset
if it's the miniusb port benQ got an extention of miniUSB like htc's extusb
if it's a 2.5mm minijack like older htc devices used you can get a conveter to 3.5mm

The only port on the Benq E72 is the mini USB one. There are no other jacks. The problem is that both sides of the metal housing within this are curved so the HTC one (with one side of the miniUSB adaptor straight) wilkl not fit. I did manage to find and buy an adaptor that was branded Samsung and when I fitted it into the miniUSB socket on the phone it would not work. The music continued to play through the rear speaker even though the adaptor was connected. My supplied headset connects to the phone through the same miniUSB paor but again the metal housing of the miniUSB jack is curved at both sides. I hope this explains better.

as i said then miniUSb should not alow audio at all on the device
and htc use extusb which have more legs then miniusb so if it dont fit
it should not be because of any curves
does your benq device not alow headsets at all ?
if it does how are they connected?

The only connector on the Benq E72 is the miniUSB port. In the attached pic you will see the connector for the wired head set on the left and the miniUSB to standard USB for connection to the PC on the right. I looked inside the silver housing of the connectors on both cables and they seem to have 5 pins along the top (widest) part with the main section being hollow. Now the miniUSB housing on the actual phone does have a plastic inside with 5 pins and , I guess, more connectors along the top of this for the 2 cables. I am to assume that the plastic insert in the phone itsaelf is for the electric charger. There is nothing more that I can give you except to say again that the miniUSB is the only connector on the phone.

if it support headsets connected to the usb connector it must be using some sort
of special usb connector like htc's extusb
i would look at their site if they sell converters

Thanks, as I said the only way to connect the headset is by the miniUSB port so it must support audio. The issue is that the HTC miniUSb headset has a curved side and a straight side so it will not physically fit into the Benq E72 connector. I did get my hands on a philips miniUSB that did fit into the socket on my phone but the music still outputted to the rear speaker of the phone. So, my question is, is there different types of miniUSB wired internals? It would seem so. And would anyone know which would work for the Benq E72 windows mobile poweredsmartphone?

@ 17-apg,
Sorry for this off-topic post. Im planning to buy benq e72 because my o2 xphone2 is too old. Can you please give brief review of the phone, as a user. Is it true that it is laggish? Thank you.

No problem ,,
I have the device for over 2 months now and like it a lot. Had a HTC S730 before which was thick and cumbersome and I didnt really need the keyboard. This phone, in contrast, is very light and thin. It runs WinMo 6.0 and I do not find it slower than the HTC in any way. On reflection maybe a little faster even. It is very competively priced as it includes bluetooth, quad band radio and wi-fi. The bluetooth also carries the A2DP functionality. The screen, whilst a little small at 2" is very bright and clear. The keypad has large buttons and is very tactile and positive when texting.There's a 2 meg camera included as well as the microSD slot with a max size of 2GB. You can, however, with software, increase this to the norm of 6GB which I have done. Also the rear speaker (built in) is a reasonable size and therefore can play a decent sound for music if you are travelling and in a hotel room for example. And finally, it has little important assets like the ability to turn on auto redial, a button on the left side which when pressed and held will open the text messaging in a send window. There is also the facility to adjust the screen brightness as well as an internet radio and ringtone editor. All in all, for the price, I definitely recommend this phone. I have bought four more since for friends of mine. They paid of course!!! Now all I need is the miniUSB to 3.5mm audio jack sob sob...

Can you tell if a lanyard can be linked to the device - and where? On all available photos on the net I have not seen any holes for fitting the lanyard to :-(
I am really tempted to get that one as well - escpecially as it is the ONLY (!) smartphone with only a normal keyboard that can use microSDHC cards (after installing updated drivers). They seem to double in size every year - and if the standard is fully supported 6 or 8GB (as reported sucesfully) should not be the limit.

Lanyard
Yes, you can connect a lanyard at the top of the phone. If you can see the top view of the device there is a little hole there. You simply slide off the back cover and fit the lanyard to the designated area on the main body of the deivce (very easily) and then slide the back cover on again.
Now we just need a cooked 6.1 rom for the device!!!

Thanks - I found a set of pictures at a Taiwan Review site (http://www.eprice.com.tw/mobile/talk/?prod_id=2621&tid=3430647&page=1&list_page=1) - this tells it as well
I was only looking for a small device that can read memory cards > 4GB and this is the one now. Otherwise my Tornado in the house of a Robbie still perfectly fits my need. I also tried WM6 and WM6.1 on that - but fell back to the original WM5 there.
Just can't wait to get it in my hands - it was really a bargain on ebay. Search for benq E72 there and you will see a guy in London selling refurbished E72 for just 69 GBP (9 of 21 left). I just could not resist for that price, sigh...
BTW - on topic: did anyone try the Motorola mini-USB connectors - for the Razor and alike?

I dont think so. DO you habve one that you coulkd try when you get the phone? If so, let us know here cause I would really like to use my own ear buds.
BTW I think you will love this phone! It really impresses me. And also Expansys anre selling brand new ones for about £90.00!!

Is there a WM6.1 for this? Thanks.

Benq E72
Not thatI am aware of. I know that another avid fan of the E72 has requested ROM cookers to try to come up with the 6.1 version bit I am not sure if anyone has taken up the challenge.
I hope that it will happen soon ...

I have received mine in the meantime, but the refurbished one was delivered with a non-fitting headset :-(
Well, it fits mechanically, but there is no sound at all. It looks like a cheap replica of a Motorola Stereo Headset - but also a normal Motorola does not work in this socket. So I am out of any possibility to measure the data of the socket to build an adapter. I complained at the dealer - hopefully there still is a working headset available!
Otherwise the device is nice - only English language installed though for menus and T9.

With some help from Taiwan - the USB wiring for the headset is identified, see my blog article at http://tobbbie-benq-e72.blogspot.com/2008/12/hacking-usb-headset-connector.html for more details. The main information is:
....So the final result is then for the numbered pins of the USB connector (1-5):
Must be connected with a resistor less than 200 kOhms to ground (pin 5). The voltage will rise briefly to battery level but then drop back to 0,16 V to stay there. I suspect that accepting calls with the headset button will introduce new functionality here...
Speaker channel (l,r not checked, source indicates right here) - must be connected to a speaker or a pulldown resistor at device-headset connection time.
Speaker channel (l,r not checked, source indicates left here)
Microphone channel (checked to work with Audionotes)
Grounds
So luckily no complicated electronics - get your soldering irons ready!
BTW: have still not received the original headset :-(

External wifi antenna

Hello,
i want to connect external wifi antenna to S620 and i need some small help with that.
I dismantled the phone and removed shields from all ICs.
On picture 2 and 3 are Texas Instruments WiFi chips.
On picture 1 is other side of the board, with some metal piece and connector, which might be external wifi connector.
The connector is at opposite side in left bottom corner if you look at image 2, between PASS sticker and mounting hole, at the corner of large PCB ground pole.
Is that metal piece integrated antenna?
That connector is probably not U.FL.
Anyone know what type of connector is that?
Thanks.

Not sure but follow the link below for the service manual, it may give you some insight:
http://forum.xda-developers.com/showthread.php?t=402998&highlight=service+manual

if you managed tu connect it, let us know everything...
hope you can do it succesfully!!!

Ok, so i looked at the service manual, the connector is diagnostic (RF measurement) type, with switch.
MM8430-2600RA1
Probably will be in all HTC devices. So i will try to search on the forum, if anybody done this on different phone.
See page 9 and 10 for switch schematics and pinout

There are "probe" cables for it, but the probe connector is too big to hide under the cover.
I have a friend with experience with SMD, so i asked him if he can desolder it and solder pigtail with RSMA.
Cable can be taken out of the phone by using free space around hole which covers the GSM antenna connector.
I verified that by putting the cable in and closing the phone.
I also tried to hold stripped cable on the connector, with attached directional antenna and i picked up the APs in that direction, so it is working. (and really well)
The problem is that ground poles of the connector maybe connects ground to the power button, so after desoldering, it might not be possible to turn it on...
The safe way can be removing that piece of metal (yes, it is wifi antenna) and solder pigtail instead of it.
It should be simple, because under it are only two "paths" in PCB.
However, the best way is probably to solder it on opposite side, there is a PCB path from Wifi chips, going through the PCB, ending on middle pin of the connector.
But that cannot be done, because there is no way how to get the cable out of the phone.
I still prefer desoldering the connector, because it is placed "before" the antenna, so connecting it there would give a bit better results.
Edit: i searched the forum a bit, but all i found is service manual for Diamond, which seems to have U.FL connector. But i will not buy it because of that, only maybe when it will cost 80 USD like S620.

My Tbolt Car Mount Install Acura MDX

I just wanted to share my car install experience. Notice that I only used the holder portion of the mount, and I cannot swivel to landscape mode. This works for me since I already have built in Acura navigation, and I mainly use my Tbolt for streaming MOG radio which is portrait mode only. This install location works perfectly for lack of glare, cable placement, accessibility, and allows me to keep my focus on the road.
** note: I used an agressive mounting tape capable of holding up to 5lbs and dealing with high temperatures. This is available at Home Depot in the paint department for $4. I mounted the car holder directly to the fake black wood panel that has a glass finish gloss surface. PLEASE do-not blame me if you ruin the $95 panel should removal cause the fake wood to crack, etc.
1- The car mount is at Verizon stores & online part # HTC6400MNT for $29.
2- The micro USB port on the mount has two metal dimples that are evil and require WAY too much force to install & remove the Thunderbolt. I recommend using a single edge flat xacto blade to remove as much of the dimples as possible. Once removed the Thunderbolt slides on and off the mount properly.
3- ******* Before mounting!!! Attach the micro USB power cable & route the audio cable and choose a location that allows the mount to remain flat against the surface & gives the audio cable enough play to be connected & removed.
4- Prep both surfaces with alcohol to remove any surface contaminants.
5- Remove the double side adhesive mounting tape covering and carefully align and lightly press the mount on ONE tiny leading edge only... allowing you to slightly adjust alignment prior to fully pressing the mount into place. **It's strong adhesive and you only get one shot so be careful.
This process has worked perfectly for my needs, and the mount is rock solid. I have a full view of the screen from my seating position, easy reach to the display, and as much as I wish the micro USB port on the mount passed audio.. it's really not a big deal dealing with the audio plug.
I hope this helps and streaming 320Kbs from MOG's 10 million database of music over 4G is such a thrill. They currently have a major Android player bug but an update will release soon.

Wow.. looks good!

Dude MOG on Android has sucked since day 1. Hopefully they will get it straightened out one of these days, I gave up.
Nice job - looks very similar to mine except I went horizontal down by the AC controls (Explorer) and switched to the Google Car Home - it is sweet. I like the 90 degree cable - where is it from?

6 foot 3.5mm male to RCA male cable
I got very lucky and found this at Radio Shack... even the inept sales guy kept saying it didn't exist... then I located exactly what I needed on his rack It might be easier to find it online & get it shipped. If I can pull the package out of the trash I'll replay to this thread with the Radio Shack part number.
The clearance between the car mount plastic & the 3.5mm jack of the Thunderbolt is very tight. Fortunately this cable has a thinner section closer to the base of the metal jack allowing it to clear the plastic of the mount.
Re: MOG... yes I'm relaying email to their Android staff daily. Fingers crossed as the audio quality & features are much better than Pandora One.

Google car home, is this the same as car dock home? I searched androlib and couldn't find it. Thanks

looks cool

It's the one made by Google, it's the best - very customizable. You won't be able to find it via market on your phone since it is "incompatible" because of stupid sense. Just download the apk and side load via USB or dropbox. when you choose the car panel app it will prompt you for which app to use - choose the Google one and set to default. Then when you put the bolt in the dock, it will launch google car home.

Thanks I'll track one down. I have a regular coil cord but want to hide the aux cable like I did with the power cable. Plus it sticks out just enough to hit my knee - the 90 degree will do the trick though.

Radio Shack 3.5mm to RCA Cable
Goto their website & search for 42-492 and it should come up.

No matter what phone dock I get, I always adapt it to a vehicle specific mount. I hate suction cups and vent mounts

I have my set up nearly the same only in the left bottom corner of my windsheild... I long ago hard wired a dual cigarette charge port to the inside of my dash and have routed power to a couple differnet devices and places using standard car chargers and makes the install seemless...
The next step in my install is to find a 4 conductor 3.5mm male to 2 female 3.5mm adapter or make one myself (one mono and one stereo on the female ends) and hardwire that to a mic element I have and the rear aux input of my car stereo... hopefully this setup will yeild much better speech recognition and usable docked speakerphone calls without buying an expensive bluetooth setup.

nice looking setup

I'm thinking about getting this mount.... What's your thoughts OP? Can you charge the phone? Looks like the bracing covers the USB input.

Kudos for a job well done!

Definitely saving this thread. That's a genius idea. I'll be doing the same with my car soon I'm sure.

Hi Guys,
Excuse my brief hijacking of the thread, but I feel this relates to the discussion.
I have recently released a new media player for Android, and the focus is on easy browsing, huge album art and a "no-look" playing screen that let's you control the functions with gestures. There is even an option to keep the screen on if connected to power. Works great in the car.
It's called simplePLAY, and you can see it running on my Thunderbolt here:

Sorry for the interruption.
