Ok, I want to use the XDAII in the LandRover for mapping, it is noisy in the truck, I also want to play MP3 WMA files via the car stereo.
I have a Garmin eTrex but am willing to get something dedicated if the price is right.
I want a cradle for the XDAII that will hold it securly,
I want to power/charge the XDAII and GPS
I want to get the audio out of the bottom connector into the front of the stereo (3.5mm socket) for music play back (poss hands free phone too)
I still have various bits of hands free kit from when I used to fix 'carphones' in the early 90's. It would be nice if i can fit a mic in car for voice dial and calls too.
If the info on the tech page is correct on the bottom connector it would appear all is straight forward to do myself, However we all know for the cost of the parts I could by something that would do what i want and more. So what will do it. I am unsure on the XDA to XDAII connection compatability.
Current experiance of produced products is a duel universal mount from memory-map, the GPS fits fine but the XDAII just falls out, not good for £30
Cheers
Hi,
I wish the same thing that you. I would like to use the Xda2 with Land Rover Discovery for mapping together my Garmin 3+.
To do this maybe we have to make a serial and power cable or find someone who can make it.
I think the pinage for xda2 is slightly different than the xda1. In myxda.com they said: "Most accessories are not common to both except for the car charger".
If someone here can help us to know what the correct pinage for xda2 than we can make one.
Or we can buy a serial cable from O2 (I am oredering one now) and check what is the pinage used for it and mix with the car charger adapter.
what do you think about it?
Charger from xda1, serial cable, gps, usb cable (charging problem) all work with xda2, cradle also works but you need to shave a little off the inside or you will mark your xda2. I have an arkon cradle/speaker, 2 usb power jacks, speaker jack with 2.5 to 3.5 converter from xda1, this works with xda2 but the rf break through from the phone to the speaker in the cradle is atrocious, i wish I knew how to fix that problem because when you receive a call you have 10 seconds or more of rf noise before you get to hear or speak to the caller, other than that it is fine and comes with lots of different mounting options.
pinout
When I get chance Ill get my scope on the pins and work it out. Ive had my eTrex working, used the standard serial lead for the XDA2 and the eTrex, just made a null modem adapter to connect between em (info on memory map web site) Works well but you have to dissable beaming as i think they share the same comm port.
I was going to buy the eTrex connector to bare ends from Garmin but it doesn't carry power only data!!! typical. Have thought of getting one of the dedicated GPS units.
So the next best option is to have a cable from the XDA2 to a small box, this will have TX/RX audio, power and data. The box will have a PSU for the XDA and a cigar socket to for the eTrex standard lead. Id rather not chop up the lead as it cost silly money.

Sounds like this would be accessory number 1 for anyone with an XDA2 and a car.
I've also got an eTrex, and I bought a serial/power Y-shaped cable last year for it, so they are available. It has a cigarette lighter plug to provide the power, and a serial output too for my laptop. Let me know if you need details - seems silly to buy a new GPS just because you can't get a combined data/power lead for it. It cost me £24 mail order, IIRC.
XDA connector
I need to find a UK supplier of the XDA connector, this would get the cost down. The easy way would be to buy the in car charger, strip it, mount the charger in the box, replace the cable with one that will do all the connections.
Ill try and play, get it set up and post somthing on here

PSU
PSU is short for Power Supply Unit. the bit that powers/charges the unit.
Sorry im not used to multi language conversation.
PSU
No problem!
I will learn a little bit every day
I am also currently looking at my options as like you TDIpower, I am trying to use the XDAII in a noisey landy.
I am interested in the parrot ck3000 which according to the blurb connects your phone etc via a bluetooth unit into your stereo unit. I have not looking into all the issues but I assume you would be able to use the phone/navigation and MP3 via this unit through the vehicle speakers to be able to hear whats going on? Mind you when I'm going a full tilt I can hardly hear the speakers either??
I know a couple of others on here have the parrot unit so mybe they could shed some light on this??
Cheers
sdio fm trasnmitor
i do not know if it is exist (sdio fm trasnmitor) but this will be a good solution for this case!
Hey,
Sorry to bring up old posts, but has anyone found a solution for Mount, Power, GPS (etrex) and Audio?
Dave
Have you seen this one ?
http://www.seidioonline.com/ProductDetails.asp?ProductCode=BD-SMGF1XDAII
A friend of mine bought one for his iPaq and it's brilliant, just like a cellphone cradle, slide it in, and you are ready to go.
Hi
What you are asking for is available, apart from the sound in the form of the carcomm cradle http://www.totalpda.co.uk/product4738_0.aspx.
According to the connector wiring on this site you should be abale to get sound from the bottom connector, but what the connector page fails to tell you is you only get sound out o fthe bottom connector during in a call, so its no use for MP3 or Navigation sounds. Currently I am using the jack plug which is a real pain to plug in. See http://forum.xda-developers.com/viewtopic.php?p=50643#50643
Re the Parrot CK3000, I have just taken one out of my car as it did not work with the XDA2 if you have installed bluetooth tools. And without bluetooth tools the bluetooth GPS device would not work. Also you cant currently send sound over bluetooth apart from when in a voice call.
If you find a solution to sound from the bottom connector please dont forget to post.
Good luck
JustinP
@justinp: There appears to be A way to get all sound from the bottom connector.
The T-Mobile MDAII Carkit (QTek2020 carkit and the Yeti carkit are the same make) do just that!
Unfortunately I have this (cheaper) XDAII / iMate (Expansys-sold like) carkit wich only give in-call audio via the bottom connector.
There is someting with pin19 and pin9 (I read on the german www.ppc-welt.info forum).
pin19 must be grounded
pin 9 must NOT be connected (it is on some carkits thus messing up proper operation).
Now if someone can verify this!!

Hi was looking on ebay for a gps craddle and receiver. Is any make better than the next, or is there a better place to spend my money?
I am after a receiver to run Tom Tom5 I don't mind if I need to permently wire it into my car. With the cradle just want it to charge my phone and have a speaker output for tom tom/handsfree would be nice.
Too many to choose from.
Do you mean an integrated cradle/gps receiver? Personally I would only ever buy a bluetooth receiver as it means it will be compatible with more that one device, and means I can get any PDA I like that GPS software will work on.
If you just want a bt receiver, and a suitable cradle, then look at the Arkon mounts. They make everything from cheap vent clip units, ro tripple mount window hanging units, to permanent screw fixed units, both with, and without powered speakers.
I find the speakers on my Wizard, and Universal, and my previous Magician & Alpine loud enough that I didn't really need the added powered speaker with the additional cabling going everywhere.
it depend on what device you are using for somthing like the universal tytyn oe kjam then you wont be able to use a a gps cradle you ca only use a bluetooth gps for these devices.
have a look at the holux cr100 the connector at the bottom of th cradle can be changed to suit a number of pocketpc's
i would also search brodit. they do wired cradles. Still think a separate cps reciever is the better way to go with a cradle for the pda.
I have an HTC P4000 (Canadian version of Mogul / Titan) but this applies to all phones on here I think as I'm looking for a car mountable solution (and most are compatible with all of these phones). I am wanting my phone to turn into a type of entertainment device in my car. Firstly, what type of cable do I need to hook up my phone to my existing car stereo system? Obviously it needs to be a cable that goes to the (RCA?) input on my deck. But is there such a thing as a cable that goes from mini-USB to RCA or will I need a mini-USB to headphone jack converter first? I also want battery charging capabilities, and a nice easy way to see the screen on my phone for movies, video clips, etc. so a car mount would be nice. I am guessing an all-in-one solution to the functionality I want is pretty common, and if so is there any car mounts that anyone would recommend based on your own use? 360 rotatable would be nice.. Linking straight to eBay would be nice too
Anyway, any advice from anyone with personal experience with these car mounts would be awesome. Do the cables seem clunky with a car mount? Would you go with a windshield mountable or just something that clips to the vents? What do you think is best from personal experience?
Thanks!
A similar question has been asked on modaco but I don't think a solution was found. Therefore I am going to ask if this would work here.
Is it possible to connect a micro usb (male) to mini usb (female) adapter up to this thing (HTC 4 in 1 adapter: I can't post link because I am a new user but just search it on youtube). This would connect to the tg01 micro usb and provide a 3.5 mm audio out in addition to a mini usb connection where one could potentially hook up a charger. I was thinking of testing this out as it would cost about 10-15 dollars but I do not want to damage my phone in the process. I have no electrical engineering knowledge but maybe someone else can explain if this would work before I order anything.
On a side note: I order samsung WEP870 bluetooth headphones on sale as an alternative to this. Note sure how sound quality is but I will try answer any questions you guys might have.
Any input is welcome.

I was heavily involved in the discussion running on MoDaCo you refered to; unfortunately there has been no breakthrough on this issue to date.
I did look into the the HTC adapter you mention, but it actually uses the proprietary HTC ExtUSB plug on the input end (connecting to the phone) and NOT a normal mini-USB. The ExtUSB has 11 pins which include a discrete audio output (being used to feed the 3.5mm jack socket) and also hard-wired power (used to accept the charger input).
In the case of the TG01 uUSB socket, it is too 'intelligent' for its own good. Every function, charging, audio out, USB data transfer, etc., is under procesor control. Different functions are triggered by the device 'seeing' a certain resistance across the sense pin and ground; depending on this the processor then configures the use of the socket pins accordingly.
I am after what you are trying to achieve also; there is a chip supposedly available which is intended to fulfil exactly this functionality, but I've been unable to find any devices on the market which use it and attempts to contact the manufacturer with a view to getting a few samples to try and build an interface have so far been unsuccessful.
I've attached a couple of documents which explain the uUSB Charger Adapter and also the chip spec sheet for reference.
View attachment MC34825.zip View attachment batt_charging_1_1.zip
If anyone else knows anything to help move this one forward, will be much appreciated !
Thanks for the nice explanation,
Hopefully one day there will be an adapter that can make this possible.
Hello everyone! My name is Patryk Andrzejewski (don't try to read my name if you're not polish), and this is my first thread on XDA.
I am studing electronics on university of technology so i'm pretty well with all kind of electronic stuff.
What i'm trying to do is "x-ray" the usb port in our TG01.
My basic targets is to find way to charge the device while using USB HUB or while listening music. If it's even possible to do.
Right now I know how to connect TG01 to amplifier by 3.5mm plug. Generaly most amplifiers have high impedance input while tg01 expect low impedance earphones to switch usb port to audio output. So what we need to do is take two resistors with the same resistance around 10k Ohm and connect them both between ground and both signal channels in male 3.5mm plug of the amplifier. This should do the trick. You can experiment with resistance but it should be as high as possible to not interfere in sound quality, but if it be to big output won't swich or sound would chop on high volume.
Basic usb cable have four wires plus ground. While micro usb plug have five pins. This extra pin is used to tell device what cable is connected, hub earphones charger or pc. It can be done by two ways, in each cable this extra pin is shorted to diferent other pins. Or it's connected by resistor to ground or Vcc.
What i need to do is determine how it is in our devices and if it would be done make a cable what will allow to charge while using usb to other purposes.
I can also help with porting microusb-3.5mm cables from other devices to TG01, just what i need is this cable, it's schematic, connection route with insides picture or small donation to buy it for tests.
Or eventualy I can make solution how to do it yourself.
Right now I waiting for a pack with new empty microusb male and female plugs to do some tests.
If someone have some experience with this please share.
Also it would be great if someone will port me on to usb switch driver.
Feel free to talk to me on priv.
Thread will be updated...
Hi @patryk,
Welcome to the TG01 Forum.... especially on this particular topic - if you can find a way to get multiple function via the uUSB port simultaneously, that will be great
There have been various attempts at this before, but in practice the only route seems to be using Bluetoth for audio while either charging or using the port in host mode.
I did a piece on Brighthand a while ago on connecting an external hard drive; there have also been discussions on MoDaCo and later on XDA (down the Accessories thread.... one is here and I think there may be some earlier than that). There is a link in the XDA post to a Freescale Smiconductor chip schematic. This is supposed to be able to (externally) support multi-function usage - ntended to be used by 3rd Party manufacturers in eg. a car kit, but as yet I am not aware of any such accessories having been released. If/when available would be suitable for any of the modern crop of uUSB based evices, though I think many car makers have opted for Bluetooth connectivity instead of the older style fixed car kits with cables.
Acording to pdf from your link I'm right, its all about one resistor. It's entire possibly to do this.
Tomorrow morning tests...
Thanks
oh I cant wait so:
rid_f: >220 kOhms
rid_a: 122-126 kOhms <-- this is what we're interest in
rid_b: 67-69 kOhms
rid_c: 36-37 kOhms
rid_g: 1 kOhm
These res val has small tolerance and ar not typical.
rid_a resistance is used to switch to charge device from charger and use usb for earphones or hub!
earphones - yes, but headset - not sure I must check first where mic is connected
here it is Dummy cable schematic:
Here are some related illustrations:
Schematic of the uUSB standard audio accessory control:
View attachment 505996
Picture of the supplied Toshiba earphone adaptor pcb:
View attachment 505997
The mic is connected to pins 1 and 2 (White and bare Cu)
I have made up several 3.5mm audio adapters using Neutrik 3.5mm jacks with 10k resistors fitted from D+ and D- to 0V common:
View attachment 506008
This ensures it will switch to audio out when connecting to external speakers with or without a ground-loop isolator transformer where typically the external device will have too low an impedance for the TG01 to recognise.
Shorting out D+ (Pin 2) and D- (Pin 3) causes the TG01 to go into Charging mode.
An R from ID (Pin 4) to 0V (Pin 5) causes the TG01 to go into Host mode.
I check all of these Rid's and it seems they don't work on Tg01. No matter how i try there is working only charging or earphones never both same time.
As you say device can be forced to charge when resistor < 200 ohm is connected between D+ and D- and they are floating.
There also must be other way to do this by the driver of usb charging becouse pc link charges only when TG is on.
In TG mic an switch of headset are connected to ID pin. So this first schematic of yours is about Toshiba accesory ?
Technicaly charging while using audio out is possible becouse VBUS pin is free in headset.
I'll do some other tests tomorrow..
Hi!
Any news since February?
I will find answers on many questions by reading this document

It is a good document, but iunfortunately leaves many questions unanswerable.
In Section 6.4 it shows a schematic of an Accessory Charger Adapter which is essentially what we need to achieve simultaneous charging and audio out (or other functions). It does not however give enough detail to implement. I have previously identified a Freescale chip which has been designe dto do this job, but hae been unable to identify any source from which to obtain one. In essence this is aimed at the peripheral manufacturers' -who might wish to design and market eg. a hands free car kit to which you could connect a microUSB On The Go spec device. However so far as I can discover there are no manufactureres who have as yet brought any related device to market. If anyone happens to have found anything somewhere across the globe - please shout !

Kevin
