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.

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.....

I used to have a XDA2i and was always aware how flimsy the dock connection was. What type of connection does use USB or some other type.
Thanks
Clive
Artemis uses Mini-USB which is becoming the standard choice these days, its quite robust, small and saves you lugging around dozens of different chargers and cables when on the road. If you are looking for a device that uses standard USB, then I am not aware of one, way too big - Mike
Mini usb was what i was on about.
Thanks for the info

with all the coverage the motorola laptop has been getting these days (google: motorola lapdock rikomagic or motorla lapdock raspberry pi )
I got one to toy around with it my self. I'd really like it to work with MHL devices. Thats the moment I found out that MHL's micro usb in is to charge the device and get the HDMI out to work, but doesn't pass though and more usb data though. I imagine the bandwidth is too great.
So as a consolation I thought it would be cool if the lapdock's mouse and keyboard were bluetooth, then i could connect to its display with hdmi, and control the phone with the bluetooth input.
Does anyone know if there is a generic usb device that allows you to connect a USB keyboard and mouse and then transmits though bluetooth? alternatively does any one know of any relevant mods that might help me hack this together?
The problem with MHL is that it uses the electrical path from the USB connection.
The problem is not bandwidth, it's wires.
All of the funny things that plug into a micro USB connector just use the same 5 pins that are already there and repurpose them.
This includes "Carkit", which is the analog headset/ handsfree connection or MHL.
usb flash is also possible to connect and then not get what you
If you wanted to be really hard-core you could add another micro USB connector to your phone.
You'd have to pick off the USB signals as they come out of the PHY interface and before the main connector multiplexer.
Or you could get the guts out of a trashed BT keyboard and wire it to your Lapdock keyboard.
You wouldn't have to get the layout correct, you could just fix /system/usr/keylayout.

I looked and haven't found one. However, during the search I found the KBtalKing Pro mechanical keyboard that solved my problem (well, when it is officially released next month)--it will allow me to use it as my main desktop keyboard (which should be great to type on due to the use of mechanical keys), and also pairs up to 10 devices via Bluetooth as well as one main USB device (probably the main computer). Looks like I'd be able to type on my Android, iPhone 4, PC or Mac simply by pressing a couple of buttons on the keyboard to switch over.
Probably not the economical USB to BT conversion you were looking for, but it's a solution and then some.
You can check out handheldsci com/kb it looks like what you want.
Hi,
Did someone try up this handheldsci adapter ?? It looks indeed as the solution to use any input device/combo without using the usb connection (very useful for smartphones).
I know this is gonna be quite a niche scenario but I'm at wit's end here and I wanted to see if there was anyone else out there who is/has struggled with this: I want to use a more power-delivery capable USB-C to USB-C cable to connect my S20+5G (Snapdragon, Verizon if relevant) to my computer (has to be the USB-C port, for various reasons) for the purposes of a USB-tethered internet connection. Has anyone found a cable other than the exact one that comes in the box that's able to consistently (i.e. no random disconnects, no "USB connect/disconnect chime") hold a connection? My entire internet connectivity (due to my location) is dependent on this so that's why the whole "no disconnect" thing is a big deal.
I've tried a multitude of cables that *should* be upgrades to the stock one off of Amazon (from decent manufacturers i.e. Amazon Basics, CableMatters etc.) but even if they deliver power more efficiently or transfer files faster or whatever, the main thing I need out of them is their tethering consistency, which they ALWAYS fall short of compared to the black "came with the phone" 3 ft. cable. These "higher material grade/better quality" cables will always inevitably kill my connection within anywhere from 10 seconds to 5 minutes of the start of connectivity.
The stock cable provides the type of connectivity I need, however I have no idea what the exact specs are for it but I'm fairly certain they aren't optimal; i.e. while my phone is tethered, the battery can't charge faster than the rate at which it's using power to do the tethering, so if I leave it connected long enough, the phone will die even though it's getting "charged" by the computer. For reference I believe the phone's USB-C port is USB 3.2 while my computer's port is USB 3.1 gen 2 and I don't think the stock cable reaches either of these standards. I've tried looking on the Samsung website but only find the exact cable I already have. Is there a better "official" version of this cable available somewhere? Or any non-official ones that are confirmed to hold the connection like the stock one?
Thanks in advance.
As an alternative, have you considered Ethernet tethering? It simplifies both the logistics of charging and maintaining a reliable data connection.
I would if I could but due to the aforementioned complete dependence on my cell data for our internet service, I have to use some...creative workarounds regarding hotspot data limits and unfortunately it can only be done through USB tethering
Interesting. How are you working around hotspot data limits? I'm curious about this, and wonder why you couldn't do something similar for Ethernet.
BTW, I use this with my phone:
Anker 543 USB-C Hub (6-in-1, Slim)
The Anker Advantage: Join the 55 million+ powered by our leading technology. Massive Expansion: Equipped with a Power Delivery input port, an HDMI port, an Ethernet port, a USB-C data port, and 2 USB data ports. Powerful Pass-Through Charging: Connect a 65W wall charger to the Power Delivery...
us.anker.com
It accepts USB PD input and when paired with a Samsung 45W charger and its stock cable, does a great job at quickly charging my phone even when using DeX over HDMI or powering USB hard disks, etc. And the Ethernet link is rock solid. For reference, I am running DUJ on a SM-G986B.
