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.

... and the 2 hours later:

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.
I bought an Exec / JasJar car charger from EBay that works fine. I also have a Holux BT GPS that came with a car charger with a mini USB plug. Does anyone know if I can use the Holux car charger to charge the Exec? It's rated output is 5v DC 850mA. My feeling is that it should be okay but I am no electrican.
Thanks
I have the same exact same question. I too have a car charger that i use with my holux BT GPS and was wondering if my Jasjar battery would get fried if i use the Holux charger.
I also got a USB cigarette lighter adapter supplied with my BT GPS device (No name). The charger is 5V and has a sticker with "IC-USB M616050 CE" on it and another sticker with " e13 020749 ".
I use the normal USB cable which came with Exec.
Anyway I bit the bullet and it works great!
I hope this helps.
Exec car charger (Supplement)
I checked the box my GPS device is a QSTARZ BT-Q770 receiver.
The important difference is whilst the USB charger is 5.3V (+ve is centre pole), it is only 500mA !!!
Hope this helps.
I have the same charger from OpenMoko freerunner but I think it fails to charge my nokia n9
Does anyone has the pinout or how to unscrew it ?

Hi all,
Has anyone already done this, or does anyone know if it is possible... to power both the XDA IIs and the Tomtom Bluetooth GPS receiver from a single cigarette lighter plug?
I have a cigarette lighter power lead for both the XDA and BT Tomtom and I'm thinking about cutting the leads in half and joining the wires so that they are connected to just the Tomtom BT GPS cigarette power cable.
e.g.
Code:
________ tomtom
/
<==------
\________ XDA IIs
Does anyone know if this should be okay? and does anyone know which wires should be soldered to which? I presume the devices will still be protected by the fuse in the Tomtom cigarette lighter plug which is good. The tomtom adapter is 2A so I expect it should supply plenty of power for the two devices, I just need know which wires to connect
From research I understand that the Tomtom cable has three wires, red, black and white. And the XDA cable has four wires red, black, white and green.
Can I connect just the red and black and ignore the others???
Thanks,
~S
I also required the use of two cigarette lighter sockets; one permanently used to power my Magician and the standard car one to be kept free for ad-hoc devices.
I bought one of these from ebay:
http://cgi.ebay.co.uk/Additional-Ca...840814193QQcategoryZ14932QQrdZ1QQcmdZViewItem
It has a socket on one end and bare wires on the other, which can either be spured of your existing socket or directly from battery. This way your devices are still protected by the fuse of the charger.
Another benenfit of this is that all cables are totally hidden under the centre console of my car- no wires to get in the way.
Of course this is a semi-permanent, 'tidy' solution; if you're not too fussed with that then just use one of those 2-1 cigarette socket adapters.
I had a IIs a few months ago and I bought a Silver shield holder with tom-tom converter cable.
This has been a great cradle and it only needs the one power supply. It also has an amplified speaker built-in, which you connect into the jack socket.
I now use this type of cradle with my Ipaq as it holds the unit very securely and is easy to get the thing in and out.
I use an "Y" cable that came with my GPS, but you must make sure that input voltage is 5V and current at least 1A, that´s what i use with my Qtek2020 and anycom gps
Thanks for the info.
In the end I chopped the XDA and TomTom power cables in half and spliced the wires together (having correctly identified them), and sealed the joint in a heat shrinking sleeve.
It works a treat

Does anybody know the specifics of how the charger for the Universal works?
The charger that I have for the car that I have (Brodit) works.
The desk cradle that I just recently bought doesn't work.
The 9V USB kit that I just recently put together doesn't work either.
I checked the wiki and noticed that pin 4 should be grounded to the pin 5 (which on the four pin USB connector is a wire from pin4 connected to the USB housing). Tried that on the 9V kit but it didn't work.
I'm very confused why my brodit car charger works but the 9V charger and the desk cradle doesn't work.
USB only has 4 pins and only 2 of them are used for charging (except for the pin 5 issue).
Can somebody explain to me how the charger works?
Is there something I else I need to do to make the 9V kit work?
Thanks.

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

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.
