I have a tomtom bluetooth gps receiver that I used to use with my xda-ii for my satnav solution. I had a car charger that charged the xda and tomtom unit at once. I have now upgraded to the Exec and am hoping to find a similar car charger but couldnt find any on google/ebay - does anybody know of one that exists?
Thanks
Allan
Cannot be of help, but looking for the exact same solution. I had an iMate JAM and a cradle that charged that (mini-USB) and had an output for TomTom Bluetooth. If all else fails I could try taking apart the adapter because it has the correct output, just the Exec won't fit in it!
assuming the TOMTOM gps receiver uses a round 5V center positive connector to charge it ( which it almost certainly would do )
then check out my posts in this thread,
http://forum.xda-developers.com/viewtopic.php?t=29351
the cradle even comes with a wire just for charging BT GPS receivers
Ouch! Thats a little pricey!
I already have a mount that holds the unit, so I am just looking for a calbe charger solution. Anyone have any links?
Thanks
Allan
in that case I have seen a car lighter plug on ebay that has a USB socket in the back, it was on £3~£4 you could then use a regular sync and charge cable to charge it
o2 shops are now stocking the car charging lead... complete with natty o2 shaped blue indicator!
To get round the problem of daisy chaining mounts and receivers, I got a great car charger - dual usb adapter from eBay (I searched for "dual usb car") which gives you 2 usb sockets for about £8 all in. Having bought this though, I'm thinking of installing a spare cigarette lighter socket behind the dash to power it from and cut down on cables in the cabin...
Funnily enough, the many Sync and charge cables for the Sony PSP would be able to simultaneously charge both a Jasjar and a bluetooth GPS unit
here is an example

Universal charger- special
The Universal as well as the Typhoon, Wizard etc. need special wiring for the mini USB. when connecting to the computer the the driver is activating the proper pins in the Mini USB socket and you can see the "charge" light on. However when connecting to a USB Poer Supply, pins need to be manipulated (some to ground or perhaps to Vcc). I'v looked into this issue many times (searching in the Internet) and could not find a proper wiring diagram. although I know for sure that they are exist as there are some Car working chargers offered for Universal / Typhoon.
In any case refering to this thread, a car charger that works for Jam/XDA2Mini most probably will not work for the Jasjar/Universal unless i is apecified as a Universal car charger.
If any of the memebers has come a cross a wiring diagram for Typhoon / Universal charging scheme it is appreciated if you could provide details.. as many of us would like to build their own car charging units.

Dude, what are you talking about !! I use the sync lead from my kodak camera to charge my JJ from my laptop it works fine but is slow (my laptop hasnt got much umph) and the same goes for the PSP power lead I mentioned earlier, I use that in the car with my cradle that happens to have USB sockets in it, (pictured in another thread)
It seems that either your usb lead has the proper connection to fit the requirements of the JJ or I am doing something wrong that I am not aware of.
Here is the test: Just take a Powered USB Hub, connect XDA1, XDA2, XDA Mini, XDA2S (all the models that I could test right now) and It seems that the Powered USB Hub can charge these devices.
Now connect the JJ (I suggest with a traditional USB syc cable that comes with either ..) and NADA I got no indication for charging .. than connect the HUB to the your computer which has the ASYNC installed and you see that immidiatly the JJ is being charged. Both feeding measured at 5.15V.
The Typhoon behaves the same for me as well.
Further more, I have few USB chargers (other than the one equipped with the JJ) which is in fact a PS with a USB port . The result of connecting the PS through the traditional sync cable is "No Charging".
The same applied to many Car USB charger that I'v tried.
Perhaps your Kodak sync cable is special (in fact I am looking for the schematic diagram of a cable like this)?.
I tried (just now again) also with Dopod 828 and it seem the same (no charging unless it is connected to the computer).
Please double check your charger cable and try th sync cable that comes with the JJ.
I dont see why kodak would have used a special sync lead, because on the kodaks it is used for data only (power comes in via a diffrent connector) when I get a chance I will buzz out the cable for you !!!
PS I think you shold plug it in and wait, mine starts charging instantaneously when used with the mains adaptor which has 1 Amp of current available, but takes a min or two to start charging when I am using my laptop/in car charger, both of which only have 500mA available.
Car Charge
From reading other threads, Pin 4 in the Mini USB is shorted to ground and that's probably turn on charging ..
I suggest that you read threads about the power charge / car charge in other forums... here is an example I took and although it talks about the Typhoon it is relevant to JJ as well and it suggest to connect pin 4 and 5 to ground. I can't have a good explanation why your JJ starts to charge after 2 monutes. I suspect that it has nothing to do with the current that can b drawn from the PS.

Here's what I've found on modaco.com forums, posted by richwookie on Oct.4 2004:
QUOTE >>>
...I've hacked open my C500 mains charger (quick, where's the superglue), and sure enough there are only 2 wires leaving the box to the mini USB cable, GND (black wire) and VO (white wire). However, after very careful probing, with a very tiny probe no less, I've established that the GND wire is connected to both pins 4 and 5 of the mini USB connector.
Now usually pin 4 would be not connected to anything as pin 5 is normally GND. So next I probed the C500 data cable to see if pins 4 and five of the mini USB were connected together. They weren't of course.
So what does all this mean?
Well, from what I've discovered I conclude that the C500 will only charge if:
1) There is data on the line (even if it isn't saying anything :wink: )
OR
2) Pin 4 of the mini USB plug is grounded.
So what's the solution to making the generic car chargers work?
Do nothing to the car charger. Mod the data cable so that pin 4 at the 'mini' end is connected to ground.
This IS all speculation and I suspect that it is easier said than done. I haven't yet hacked open my data cable, but I expect there are only four wires in it, and the only way to ground pin 4 (mini end) is to somehow bridge them at the connector. I think that is beyond my soldering skills (have you seen the size of the contacts on the plug?!) but I may give it a go anyway.
Anyone else want to try? Let us know here.
<<< UNQUOTE
... and the 2 hours later:
QUOTE >>>
Posted from my SmartPhone while it is charging in my car using a 1.49 cigarette lighter USB adaptor and my newly modded C500 data cable!
I'll let you know if it still works as a data cable when I get home. ;-)
....
Modded cable doesn't work for data now.
When I connect it to the PC it just charges. I suspect that when the phone is in 'charge from adaptor mode' it inhibits the data lines.
<<< UNQUOTE
Well, I guess it's simpler to mod a USB cable, than either carry around a charger, or install Activesync everywhere.
With all this chat about modifying pins etc call me naieve but why not just buy a dedicated charger from expansys or an o2 store ? both cost between £10 - £15
:shock:
Just an observation I have made... I have an O2 EXEC, and charge it quite happily (sort of) with the Standard USB Synch cable and a Car Lighter Socket USB thingy.
The only thing is... It will NOT charge if the EXEC is on (screen lit up) when the USB lead is connected or power connected. Switch the device off, connect the lead, and the charging light comes on.
I find the same when I connect it to the computer with the Synch lead too. It won't connect to ActiveSync or Charge if the EXEC is on when connected.
Hope this helps.
Hi,
I am looking for cable that I could use to connect my JasJar PDA (USB mini port) with GPS (USB mini port) and car lighter. This cable should transmit data between PDA and GPS. Also it should power PDA and GPS from car lighter socket. Look at attached picture for better explanation.
Do you know where I could buy it?
Best regards
Marek S
Cześć!
Myśle, że nawet jeśli masz taki kabel, to będziesz mieć problem. And there my Polish runs out!
(trans: Even if you had such a cable, you'd still have a problem).
Or at least I would assume so... Even if you made a mini usb to mini usb cable with power spliced in from a car adapter (easy enough to do after all) then you would still have the problem of persuading your pda to use the usb connection for rx/tx gps data, which I would have thought was a drivers problem...
Anyone?
Hi,
As I read on some forum this device can work as USB host and WM 5.0 has many drivers also for GPS devices. Is that true? If it is, problem how JasJar will communicate with GPS is not a problem. The problem for me is that I cannot make that cable myself and I need sombody help.
Best regards
Marek S
Sadly, this device cannot act as a USB host... I am frankly disappointed that they decided not to implement it, but I guess there always has to be a reason to upgrade to the next model!
I'm afraid I don't know about WM05's support for GPS devices connected via USB, although I think I have read in other threads that people have tried without success to connect GPS receivers to their Universals.
I bought a BT gps receiver to use with mine, and am hoping to cover the cost of that when I sell my IIs, wired gps receiver, cradle etc. One thing that attracted me to the Holux that I bought is that it can apparently be used as a gps mouse if you buy the optional cable - a usb to usb mini that has a curious small plastic junction box halfway along it's length. I assume that there is some form of jiggery pokery going on in there (like swapping the 2 data lines or grounding something ) because I certainly can't connect my receiver to a laptop with a normal usb to usb mini cable.
Sorry I can't help more, but I think you may be stuck unless you can find someone locally who'll chop up some cheap cables for you to experiment with... :?
I am wondering whether if you got a Minu USB to USB B, plugged it into a cheap powered/unpowered hub, the to the GPS would it work?
If it is a cheap hub, when powered, it may have the 5V rails joined, in which case the power might run back to the universal.
However, before testing this, it would be wise to test that the USB can work with teh GPS on its own. If you do not have a mini USB A to mini USB A already and tested (I couldn't see such cables) then www.maplin.co.uk could supply you with the following, which would/should provide you with a connection if it is at all possible:
mini USB A to USB A (Standard with universal surely?)
Female USB A to USB B
Female USB B Female USB A
USB A to mini USB A (Standard with universal)
That is a lot of cables
This cable should transmit data between PDA and GPS.
WHy on earth would you want that?

Once you can prove that the PDA can connect to the GPS that way (one of the posters was not particularly positive on that) then the addition of the HUB would allow you to put the power onto the cable.

Hi Marek,
This is not going to work for DATA but this kind of cable may work to charge both JasJar and BT gps. Log in to www.allegro.pl , find covox in "szukaj użytkownika" go and buy the BT gps with the mini usb port (like G-Space GS-R238) and solder in second usb mini cable into the included car charger .
thats all...
This should charge both....ordered one and am waiting for it, doubt it'll sync though.....

Hi,
I'm looking for regular USB synchronization cable for Artemis. My Artemis was defective and HTC have replaced it, but now I have problems with connection Artemic <-> PC. It looks like cable disconnects from time to time (sometimes when I touch it).
Do you know where to buy more reliable cable? I think my original, shipped with device is connected to loose. Maybe plugs in cables made by other brands are made more solid.
Thanks in advance.
Any usb to mini-usb cable will do, just choose a more reliable looking one at your local pc store
I'm not sure if any mini-USB cable will charge and synchronize data. I saw cables only charging some PDAs (without data transfer), but charging and synchronizing other PDAs in some Internet shop.
Thanks anyway.
My standard USB to miniUSB cable does a perfectly good job of charging and syncing my Orbit.
Thanks,
I bought mini-USB too and it works without any problems (better then cable shipped with Artemis).
Hi
I am using XDA Orbit 2, as you know the headphone is connected via the USB connector as well the charger.
I am looking for a splitter or kind that i be able to connect the Headphone while it's charged, i can't use BT headphone as the internal radio dosn't support it and the wire one need to be use.
Please Advice
Thanks
G.
This device on ebay appears to do the job
it's a usb to audio jack with another USB port in the side of the jack end to which I assume you can insert the charging usb cable.
ebay item 140213905385
(USB Headphone 4in1 Adapter for HTC Tytn II P3600 P3600i)
the first picture doesn't make it clear, but if you check the others you can clearly see the charging port.
this is a UK auction, but the seller's based in HongKong so I expect it's available worldwide.
I want to connect my note 2 to my car stereo via HDMI so I bought a cheap MHL cable for galaxy S3 assuming it works on note 2 as well.
The main purpose of doing this is to see the navigation on the car stereo screen so I don't need to attach my phone on the windscreen. However, every time I connect the MHL cable the phone loses GPS signal immediately. I have tried it at home on my TV, same problem. So does anyone have a genuine adapter from samsung can help me to test if you can get GPS signal with it connected to your TV via HDMI? If it works, I may buy a "real" samsung adapter and through that cable to the trash.
Same with S3

I have exactly the same issue with an S3 - cheapo ebay MHL, as soon as I plug in GPS signal definately drops.
My cable has a standard USB plug for power, and an HDMI plug for the screen and a micro-usb for the phone. To start with I plugged the USB power end into my cheapo £0.99 USB cigaratte adapter from china. Instantly the GPS signal disappeared completely.
I have today replaced the cheap power supply with a more expensive Gifford PowerBolt cigarette USB adapter and now I get more signal, but there is definately still a drop. For instance the phone on its own will Navigate when located near my gear stick, but will not get a signal when plugged into MHL in this location, but I can navigate successfully with the phone on the dash under the windscreen with the new power supply.
I'm wondering if this supply is somewhat better than the crap from China but still too dirty.
Does anyone have any recommendations of an adapter that will give a pure power supply.
The other issue I am having here is that although my power supply can output 1 AMP which should be sufficient to support MHL, GPS, Bluetooth etc and charge the battery, the phone is not detecting this supply as AC so only using 500MA from the supply, meaning the battery drains and eventually runs out on a long journey.
I know this is due to the middle two pins on the USB side of the micro USB on the phone not being shorted, thus telling the phone it's connected to AC and to draw the higher current, my MHL cable clearly does not have these pins connected.
Does anyone know of an MHL adapter/Dock/Cable that has full USB connectivity and MHL connectivity?
Hope this sheds some light, hopefully we can get some suggestions on good quality power sources to cure the interference and a good MHL adapter with every pin connected to the phone to allow for AC power mode with MHL.

We must be using the same product. My one comes in red cable. Actually, I really like the design cos one single cable solves all issue: charge+HDMI. If I use the genuine Samsung adapter, I have to connect both HDMI cable and USB charging cable.Now I use the aluminum foil from my kitchen to wrap all three ends of the cable and it makes the GPS signal a little bit better. I have ordered some ferrite core clips from eBay hope this can solve the problem.
Stupid GPS!!

Any update on this from your end? Did the ferrite core clips work? I have found some more info that this could be caused by the fact the HDMI do signal is grounded to the external lcd display, which in turn is grounded to the cars chassis (either through wires in a harness or directly) and then the phone is also grounded to the power side of things, and because both are grounded to different points on the car this creates ground potential difference. I don't really know too much about this but am told that this will almost definitely interfere with the signal. I have been advised to ensure the lcd display and the power cigarette adapter are grounded to the same point on the car. So I have hooked up a cigarette lighter socket behind my LCD and then grounded both the LCD power and the cigarette socket to the car radio harness at the same point then plugged in the power adapter into this new socket, unfortunately this has not made a difference. The next step I am advised is to ground them directly to the car chassis to achieve a better ground connection.
The problem still could remain due to the fact the circuitry in the in the lcd may cause resistance and cause ground potential difference regardless of both the phone power and the lcd power being grounded to the same point on the car.
I am wondering if connecting the ground of the hdmi port on the lcd directly to the chassis whether this may help?
Do you understand any of this? Does it make sense. Doing my head in!!!
If your ferrite cores helped let me know or if you have found a better MHL adapter that would also be good!!

hi all,
I have the same issue with my S3 and MHL that I got from Samsung.
When I just connect to MHL I see instant GPS signal drop and also data GPS/LTE drop as well
Any ideas how to solve this issue?

yes, I solved this issue by replacing black 1.0 MHL with new white 2.0 MHL I got directly from Samsung.
Samsung tech told me that for 1.0 MHL it is expected to cut signal when it's in HDMI mode as TV doesn't expect any GPS
