Hi,
I'm only 13 and a proud owner of an O2 XDA 2.
This I what I need help with.
I would like to place my USB docking station on top of my subwoofer, and connect my XDA with it (only for audio purposes only).
I've read some of the forums here, but didn't find much info. :?
Could someone tell me which pins, on the connector, on the dockingstation send the sound? I would like to add 2 cinch cables to these pins, and attach them to my subwoofer (to kind of make my XDA like an Ipod or another MP3 player, where I simply stick it into my dockingstation and start playing MP3s through my sound system).
Thanks,
Kind Regards,
Tony Schattat
Hi mate.
Note sure you could connect the XDA directly to a speaker as I doubt it would have the required power output (but I don't know much about this, just being logical).
Take a look at the following thread: http://forum.xda-developers.com/viewtopic.php?t=26489&highlight=
This guy has basically modified the headset to have a 3.5mm jack - I've then suggested (and intend on doing this) that you could put 2 standard audio outputs instead.
On reflection though, I think his suggestion may be better as it reduces the number of leads. If you then needed to split the sound out to 2 seperate channels you could use something like this:

Hi Wayne,
Thanks for your reply.
I would rather like to have a solution which is built in my dockingstation.
With alot of precision I was able to do the following.
1. Used http://wiki.xda-developers.com/wiki/Connectors for details.
2. On pin 19 on the dockingstation I placed a 10K SMD resistor (as the standard ones are too big), connected to GND, as stated in the text.
3. Using a double cinch cable I soldered them onto pins 3 (CAR_AUDIO_R) and 4 (CAR_AUDIO_L), and both GND wires to GND.
But nothing seems to work.
I used the ohm-metre to check if the 10K resistance even came up to pin 19 of the dockingstation. I does. Unfortunately the XDA doesn't turn off it's built-in speaker and microphone, as stated in the text.
This basically simulates a car-kit for the XDA, doesn't it?
Kind regards,
Tony Schattat

Hiya!
Well if yer are 13 then it seems UK Schools are way behind German ones if they're teaching you about using Ohm Meters, Resistors and electronic theory already!
Ok, overall to me this whole precision soldering and resistor checking etc is all overkill for what you ultimately seem to want to achieve.
I've just bought off eBay the little 2.5 mm to 3.5mm standard headphone jack converter lead for about £2.50. I'm going to go nip into a shop or again off eBay and get a 3.5mm stereo to 2 phono plug convertor lead.
Simple case of then slapping that into the Aux input of my Hi-Fi amplifier, or my mini deck hifi etc and playing the mp3's through that!
No need for faffing around with soldering irons, and electronic theory and all that!
Added benefit is of course that through the hifi unit, I have full control over the audio equaliser functions and so will have the full spectrum of audio frequencies to hear the music - Your requirements states you just want to connect it to a subwoofer. Low frequencies are great, but you do need the upper frequencies too!
That will all set you back the grand total of about £5, and i've assumed you do have some audio equipment with an Aux input!
For 'constant' playback, when yer battery gets flat,... just plug the charger in!
Another benefit is that you can take the leads with you on your travels and setup the same at any of your friends houses with minimal effort!
I don't see the point of the route you are wishing to take - unless I'm missing something (I got in at 7am this morning after clubbing and up at midday, so im knackered!)
Cheers!
Hope this helps!

Hi Dennis,
Well the schools here aren't all that far ahead ( I think, because I`ve lived in Australia for 6 years)!
It runs in the family!
I was able to find some handy info on some dockingstations on google, but I'm not very sure.
Is it true that the serial dockingstations have an audio connector on the rear side, opposite of the power connector?
Is the audio connector on the dockingstation the same thing as the one, which is found at the bottom of the XDA (would it disable the built in mic and speaker of the XDA and send the audio through connector on the back)?
If this is true, could I simply attach a 2,5mm to 3,5mm converter to the back of the dockingstation and attach the converter to my subwoofer?
Kind regards,
Tony Schattat

Hi there Tony
I'm still not sure exactly why you want to connect your USB cradle to play music through.... seems pointless to me..
The method I described would be the easiest for you to 'amplify' the audio output from the XDA2.
I may be wrong but I dont think the USB cradles have an 'audio output' connector at the back, it's a bit pointless as these devices aren't devised as 'audio players' - so no, you cannot put the 2.5 to 3.5 mm converter on and then connect that to your subwoofer (signal is wayyy wayyy too small to drive a sub woofer) if there is an audio output at trhe back of the usb cradle, then I never knew about it!! and same again, you cannot connect directly to a sub woofer.
Out of the socket at the bottom of the xda2 in a 2.5mm size, is an audio jack. Get the converter to take that 2.5 mm and output it to a standard 3.5mm headphone socket size. Right, at this stage you can connect 'Hifi' headphones and enjoy your MP3's that way. If you now want your music 'louder' you need to convert that (now) 3.5mm output to be able to connect it to some audio equipment that can 'amplify' the signal and play through some loudspeakers (the 3.5mm socket to Phono converter lead). That will go to your hifi amplifier in turn to which 'full range'loudspeakers are connected. You mention 'sub woofer' .. You could then attach your sub woofer to the amplifier and you will only hear the low 'rumble' of the bass frequency content of the music (again, a bit pointless!). If that's what you want then at this point all will work but then what's your plan for hearing the mid range and high frequency elements of the music?
I'm just thinking that for your final 'aim' (to hear MP3 files on the xda through loudspeakers) the method you are using is cumbersome, time consuming and pointless when you can have a 'full range' output using the method I described.
Take a look at eBay for the connectors - and you'll find you should be hearing music in no time!
Cheers! Dennis! West London UK!

Hey,
I have a question regarding the XDA II.
When I'm getting the device I would like to get it connected in my car.
Is it possible to connect the XDA II to an amplifier and play my mp3's?
I know there are a few amplifiers out there that can be connected with a "walkman" jack.
If is possible could you put some pics online where I can check it out?
Thanks a lot!
Cheers
Panja
if you dont want to get a car tuner which neat jackconnectors
and you have a tape player in the car then
http://www.digitalnetworksna.com/shop/_templates/item_accessories.asp?model=69&cat=16
this one or one like it would work if you made or got a xda 2.5 to 3.5 converter
First of all: thanks for the amazing fast reply!! :-D
I don't have a tape player in my car... So this is not an option for me...
I can buy an amplifier that can be connected with a "walkman" jack.
I had one a long time ago, I connected my walkman to the amplifier.
So is there a cable that can be connected to the XDA II and the other side that has a "walkman" jack? (So I can put this in the amplifier)?
And will this work for the XDA II?
Cheers
http://www.expansys.com/product.asp?code=PPCPADPT01
xda1 and 2 have compatible connectors apart from the pickup phone buttons
w00t!!
That's what I'm looking for man!
Thanks again, going to order that one as soon as my XDA II is in my hands :-D
Does anyone in here own such a cable?
Just want to know if the quality is any good...
If it's worth the money.
The cable itself is not that expensive but I would have to buy an amplifier too.
Don't care about the money as long as it works great :-D
Cheers
Also I would like to know when connected with the cable does the microfone still work? (so when the cable is inserted)
Because I will be using MS Voice software...
Thanks
if it does disable the mic in the xda then this
http://pc-mobile.net/pxdaa.htm
would work it have a mic aswell and a 3.5mm connector
of cause then you would have to place it in a place where
it can recieve your voice
about sound quality then should not be much worse then the headset
it's just another connector with the jack 3.5mm
it's just analog you can compare it with how much the quality loss would be if a walkmen were connected the same way compared to connected to a headset
Thanks man!!
Just a question regarding the cable with mic.
If I will use it in the car with the sound (mp3) over my speakers won't that interfere with my microphone (with ms voice software)...?
Hi just thought this idea might help:
if you have a look around the net (i think Expansys.co.uk also do one) you can get a little radio module that plugs into a standard stereo jack, it transmits your audio to a special frequency that can be picked up by any FM radio nearby. Like you car radio if you have one.
I use my XDA II as an MP3 player in my car via Seidio's iSound wireless FM transmitter. The transmitter input plugs into the XDA2's headphone jack (I have a 2.5 to 3.5 mm adaptor) and then I tune my car stereo into the user definable frequency of the iSound transmitter. Works very well.
http://www.seidioonline.com/ProductDetails.asp?ProductCode=SFTF1
This sounds very very interesting guys!!
Thanks a lot.
This is a lot more userfriendly than putting an amplifer and stuff in.
I have a nice car audio so this is very neat!!
How is the sound quality?!
Cheers
So how is the sound quality?
Before I'm buying this one I would like to know if the sound quality is good.
I got the expansys adapter but it works very poorly for the XDAII dues to the unusual shape of the 2.5 socket on the XDAII. I have to fiddle with the plug to get it to work... very annoying.
Anyone found an adapter without this problem?

Yes, with another adapter i had the same problem.
Buy on old Nokia 8110 headet, cut it below the mic and use the wires to solder a 3,5mm connector to it, On the nokia wire :
blue = Audio-L
Green = Audio-R
Red = Mic
Blanc = Ground
Good luck !
I am 99% finished on developing a car kit for the XDAIIs. The plan is to make this available for all versions of XDA, MDA, SPV etc. when complete.
At the moment the kit will do the following
Power the XDA
Has got a microphone input.
Has got speaker output of voice through the car stereo speakers
Has got speaker output of navigation through the car speakers
Connects to a wired GPS antenna - currently using PS2 connector but I'll be making an RJ11 version on Monday!
All I need now is a way of signaling to the car kit that the XDA is in the holder! :x
From the car kit, I have 1 wire which needs to be connected to 5v to power on. I also have a 5v feed from the car kit so I could simply join the wires but thats not the point.
I would like to find either of the following options.
1 - 5v feed from the XDA when in the holder
2 - Using 2 pins on the XDA to feed 5v in and get 5v out on another pin.
I have also found that on an XDAII, there is a 5v feed on one pin when in a call, but there isn't anything out of an XDAIIs in the same situation. I just need 5v when the device is present in the holder.
If anyone can tell me if this is possible I would really appreciate it.
Regards
...Spence
In order to get the carkit to work, I think you had to ground the pin instead of putting 5V to it, as specified in this thread :
http://forum.xda-developers.com/viewtopic.php?t=4829&start=75
It would be great if you could post your circuit !
Where did you get a proper connector, or did you just modify a xda II connector ?
Ciaos,
Kristof
A modified Carcomm cradle?
THe XDA uses 3 pins for the +5 Volt charger. I believe these pins are shorted inside the XDA
If you charge through 2 of these pins you might be able to use third to recognize that the XDA is inserted

Pin 12 on an XDAII goes to a positive voltage when in a call.
One thing I did notice was that the voltage does just appear and disappear, it builds up and drops off over 2 seconds,
Regards
...Spence
Thanks for the info!
Is there any similar behaviour when ending a phone call
I suspect my XDAII/iMate carkit is triggered by this signal, I would like to manipulate it in order to have the carkit amplify the TomTom directions also.
Other question: what type of mic did you use? The XDAII has quite some problems with the mic input signal (resulting is bad sound quality)
The voltage builds up to about 5v when making a call and does drop off to 0 when you end the call. Also, I don't have any problems with sound quality (although this is in an office at the moment) with the microphone.
I am using a universal car kit that my company sells, just hacked the connector off the end and connected it to the XDAIIs connector.
Still having problems, but with the car kit now and not the XDA
Can't get it to switch on/off when the XDA is in the holder and taken out!
..Spence
Sounds like you've found out some good stuff Spence.
I'm working on a similar project at the moment, except I'm using a circuit that detects audio coming from the XDA's pins, which then switches a relay to ground.. this is connected to the car stereo which goes to "Telephone mode" when grounded. Its about half way done at the moment, so I'm not sure how sucessfull its going to be.. but I'm currently having trouble with the volume of the audio from the XDA, (I haven't tried a Mic on it yet)
Would be interested to know if the XDA1 also has 5v on Pin12 when in call.. as I could revert to this if my plan doesn't work, although it would mean loosing Tomtom prompts through the stereo
Keep us updated on your progress :wink:
The other added goodie that I can put into some vehicles is a thing called an intellimute - made and designed by my company!
Linked in with the stereo, it will mute the stereo when it senses audio not just when in a call hence the Nav audio as well.
This might be useful to you - but you will probably have to but one to try it out.
I don't have an XDAI to try anything with - plus most people who I have spoken to have a II or IIs
...Spence
@swifty: When Pin 19 - Car On - is connected to GND via a 10k resistor the XDA gets into 'carkit-mode' resulting in ALL audio to be sent via the bottom connector. This will help you feed the audio to your stereo.
Together with the Pin 12 behaviour (+5V when in call) one should be able to build a carkit circuit:
Connect the audio-out pins to the car-stereo audio in or -alternatively- a seperate amplifier.
Make your car stereo go into mute when Pin12 gets 'high'
BTW, I gues you checked the wiki pages:
http://wiki.xda-developers.com/index.php?pagename=Connectors
I would like to know what mic type is used by you guys, as I read in the other thread mentioned that this still might have issues.
Thanks Edsub,
Thats pretty much how i've got it hooked up at the moment, but I think there was a problem with the amplifier I was using as the audio from the stereo was very quiet. I've now changed the circuit and will be testing it out in the car tomorrow.

To cut a long story short, I had a couple of data cables for Ipaq's (3800 I think) lying around and I got a complete car kit from stock, cut the cable off at the phone cradle end and soldered on the connector from the Ipaq.
At the moment it looks a real mess, but it does work!
Haven't played with it for a few days, but might do some more today.
FYI, the problems at the moment are car kit related, not XDA - the XDA issues are solved.
...Spence
If you need an xda 1 and or the car kit to loan for your project, let me know.
I still have my iMate/XDA2 carkit (the one as sold by ie Expansys).
There still are two things I like to change:
1. Mic quality. I allready used a better mic (Nokia style gooseneck) with a thicker wire (as sugested by Expansys): Things did improve, but I still sound like I have a bag over my head (or like I am talking into a toilet bowl according to my collegue) . . .Any help greatly appreciated
2. Only the in-call audio is send to the carkit speaker. I would like to get all audio on the carkit speaker (so I get better amplified TomTom instructions). The car-audio mute only has to do its work when in a call (otherwise you wont be able to listen normally to a conversation or ie. the traffic info on the radio)..also: any clues???
A hint: In one of the other threads on this it is suggested that putting someting into the XDAII headset jack wil get all audio out, but that is not quite workable withou drilling the cradle to pieces.
Can anyone tell me what the effect on the bottom connector signals is when you insert something (ie an empty plug) in the headset jack?
Hi all.
Great topic. There's one thing I still don't know.
Does IN_CALL pin work in XDA 2s / MDA III ?
Mine XDA IIs doesn't put anything on IN_CALL pin when calling.
I have been having similar problems with audio with powered cradles/car kits. Just cannot get the damned audio to come out of the car kit, only call audio! (XDAIIi/Qtek 2020i)

Suggestion
Why not simply have a mini contact switch in the bottom of the cradle to sense when the phone is in the cradle?, or use a simple current sensing circuit?
a VERY simple circuit would be a coil of the 5v feed and a reed switch, when current is being drawn through the coil it will generate a weak magnetic field, which could be used to close the reed switch...
Simple yet effective...
Ok guys.. what i would like to do is get the sound of the himalaya on my car stereo so i can watch a movie with perfect car sound instead of the internal speaker of the himalaya.
1st option: An FM Modulator that wil be connected through the 2,5mm jack but the problem here is i have to modify the cradle so the 2,5mm jack will fit.
2nd option: maybe a bluetoothdevice that is connected to the car stereo??
any other option??
i would like some opinions on how to deal with this one..
what i did was used a 2.5 to 3.5 jack converter (got it from hk but should be available elsewhere). then i used a an audio in-out jack (with a 3.5mm jack); plugged it into the now converted 3.5mm xda jack, then plugged the output into the audio input jack of my car stereo and there you go. almost similar to the system used for plugging in your ipod to the car's sound system. i use a bt headset so that takes of the calls. when the phone rings the music stops and the call comes in. butttttt....sometimes the media player doesn't come back on and i have to hit the play button. sure the unit is mounted but it can be a drag sometimes...
do u have some pics?
how did u solve the cradle problem blocking the 2,5mm jack input?
i am so curious!!
i'll have to take pics then. but the car mount i use is not officially for an xda unit; i just went and bought one when i was in hk for a business trip. the cradle is basic; clamps on the unit from the sides using those spring-action arms with anti-slip rubber-like material (?). the underside is supported by two stems...giving it the appearance of being a 2-legged fork. the supports are small enough so that they don't block the slot for plugging in the car charger and the microphone jack. the cradle is then supported from the back; which leads to the arm connected to the windshield via a heavy duty suction cup....well so far it hasn't fallen off... from there the 2.5 to 3.5 plug converter is around...an inch and half long maybe...the "male" 2.5 end plugs into the xda's "female" jack and at the other end is the "female" plug. the audio input/output connectors are basically similar to your vcr to tv connection; one plugs into the female 3.5 plug (connected to the xda) and the other simply plugs into the car stereo. not complicated at all if you ask me...and you don't really need to have the cradle / holder since you can just leave your unit on one of the shelves under the dash. again, similar to how the ipods are plugged into the car stereo...
ok i have a pretty good idea what it looks like but the problem i have is that my carholder/cradle is blocking the female jack connector so i think im gonna drill out a hole.
i bought me a 2,5 mm jack that i have to solder but the jack itself is too big so now i need an L shaped 2,5mm jack similar to the headphones of the himalaya...
thx for the input m8 (lol) stil a pic would be nice
I recently have gone through two different Body Glove Sport Stereo headphones with some issues. I can't decide if I have another faulty headset or if the phone audio connector is the issue. The body glove headset is similar to the headset that comes with the 8125, but it looked more comfortable.
The problem I am having is this, the headphones only play in the right side. Messing with the plug on the headset results in some quick burst of audio on the left side and pulling it out a tad gives me some faint left audio and the right side audio goes out completely. It seems the plug and jack don't quite jive... anyone else experience this? It comes with an adapter for the "bigger jack" and upon trying one of my girls iPods, they work fine with the adapter in the mix.
My application is this... I listen to MP3's while riding my motorcycle and the earphones that came with the phone hurt my ears after a while. Plus they don't have the greatest audio quality. Looking for a comfy replacement, but the above issue has me scratcing my head.
Here is a link to the headphones: here
i think...
i think you have the wrong adapter. i tried using the slvrs adapter with my 8125 and it did not work same prob as you. i went to radioshack and got one from there and it did. im most absolutely sure is the inner wiring. what happens is that there's also a connection for a microphone on the 8125 so some adapters dont work.
http://www.pocketpctechs.com/main~unit~Cingular_8125-559~area~accessories~item~PPCPADPT21.htm
ps my friend got a mono one at radio shack and it worked for him both sides. hes not a audiophile but you get the idea, it has to be the connection of your plug.
The headphones in addition to be being stereo, have the microphone too, I think the paragraph in the page you linked clears up a few questions for me:
Most manufacturers create their devices allowing audio compatibility with only their specific brand headset or headphones. We have designed and engineered several different types of audio adapters to accommodate a variety of devices. Our unique audio adapters give you the freedom to use any standard 2.5/3.5 mm. 3 conductor headset and/or your favorite set of headphones.

It would seem although the Body Glove headset uses the 2.5mm jack, the internals of the 8125 are off enough that a select few aftermarket stereo headsets with mics will work with the phone. Interesting.
Upon further examination of the jack, it is different than the one that came with the phone. In spite of the BodyGlove being a stereo headet with a mic... just like the one that comes with the phone, the connector is different enough to not with aftermarket stuff I guess. Those dirty rascals!!!
The connector on the left is the one that comes with the 8125, the one on the right is the BodyGlove.
Searched and found this old thread. I went to connect my 8125 Wizard to my cars 3.5 jack using a standard adapter and it only came left channel.
Is there a more cost effective proprietary four-conductor jack to a 3.5 mm converter than posted above at PPC Techs? I was hoping to spend a few dollars.
I'm actually using my old Ngages audio cable to get Stereo sound out of my car stereo. It works but sometimes I can't use the mic on the cell phone to talk.
When it works it's really cool, but otherwise I gotta unplug the cable and use it like a regular phone during phone calls.
Hi
Just after some input on connecting to a car stereo. My thoughts
1) I have read the guide on creating your own mini usb to 3.5mm jack plug cable and have also seen similar things for sale
2) I have seen on a car forum for the car i own a guide for making a cable connecting 3.5mm jack plug to the AUX on the car stereo (used for the cd changer).
3) I can charger my kaiser through a usb cable in the car.
4) There is obviously a power source on the stereo.
Given the above, would it be possible in theory to have a direct connection between the phone usb and the stereo that would allow the phone to play through the stereo and also charge it at the same time?
I dont want to go through the process of doing it if there is some fundamental reason why it cant be done.
this might be wht your looking for hxxp://cgi.ebay.co.uk/3in1-usb-Adapter-for-HTC-KAISER-P4550-TYTN-II-VARIO-III_W0QQitemZ190232228190QQcmdZViewItem?hash=item190232228190&_trkparms=72%3A12%7C39%3A1%7C65%3A12&_trksid=p3286.c0.m14
Of course you could. But keep in mind that your microphone won't work for most usb+3.5mm adapter. It's very troublesome to pick up the phone. I would recommend you to opt for BT route. e.g. Stereo bt headset w/ 3.5 mm adapter like Sony Ds-220 or BT head unit like JVC BT-1
Something you might have to research is alternator whine.
I made a lead myself as you described. But as long as the device was charging There would be a buzzing coming from the speakers. This went away when running on battery power and when the device was fully charged.
I also tried a bluetooth device, and again if I tried to use it while it was charging I would get the dreaded buzzing.
I still have not found a solution. FM transmitters have never worked either for me. There is not enough space between channels here.

The original mic supplied works okay for me with the headphones chopped, but its very echoey even mounted as far from my speakers as possible so would agree with the above.
Ive the same setup in my car. The phone stuff was easy, it was getting the right VAG adapter to fit my cars HU that gave me the most trouble.
I also hardwired in my charging cable to keep it tidier and my cig lighter free, might be worth thinking about.
I have made a start on this. I have wired in the cable from the Car stereo and at the moment this ends with a 3.5mm Jack Plug. I have also bought the YC A200 cable from HTC which allows connection of the 3.5mm jack plug, a wired headset and also mini usb charging. In fact two of the HTC cables were delivered to me (one ordered but 2 delivered and invoiced) so I might use one as a development cable.
So far - music plays through stereo ok, not over impressed with the quality so far but am going to fiddle with the settings. SatNav also plays through the stereo - much easier to hear. I have had an issue this morning when having music playing and satnav running that the GPS signal was being lost. Not sure if this is a problem with running the two things at once or an interference issue from somewhere. I have never had problems with the GPS before. Am going to do a soft reset and try again on the way home tonight.
I was looking at hardwiring the charging cable to tidy things up and free up the lighter socket. I was going to use the 12v feed from the stereo. Is there anything I need to do or be aware of on this?
How does the mic etc work? I know you can use the headset but I would prefer to use the car speakers if possible. We also have a number of old nokia car kits at work which I was thinking of using for the mic. Would the speaker side work if I connected the relevant cables from the headset port on the HTC adaptor to the 3.5mm jack plug connections?
Im just using the mic from the supplied headset, chopped off the cable past the mic/volume slider and mounted it in the car. Call audio comes through the car speakers.
To hardwire the charger in you need step the voltage down from 12v to the needed 5v. I took a live and earth from the back of the stereo, took apart a usb cig charger and soldered the cables into it, put it back together and hid it behind the dash. Then just took a mini usb cable from that up to the 3in1 plugged into the phone.
SRSWOWHD cleaned my sound up considerably using Pocketplayer.
Well, my experiences so far,
Got the HTC YC A200 cable
1) Playing music through car stereo works great
2) GPS works fine most of the time, still not sure what the problem is, mainly voice directions not working properly all the time
3) Charging via the cigarette lighter socket, still got to hard wire the charging
Latest development
Got a Nokia car kit mic, just had to trim the locking lugs off the 2.5mm (or is it 2mm) jack plug. The mic works fine and the caller can hear me ok. The sound comes through the stereo but is not as loud as the music but i can change this slightly by fiddling with the plug, gets louder or quieter but still not the same volume as the music.
Any ideas? Would it be that the HTC adaptor is expecting the htc wired headset?
removing alternator whine / hum
Finally solved the alternator whine / hum over at my place too. Key is to take the power for the charger directly from the power feeding the car stereo. That way both the stereo and charger reference the same ground which eliminated the ground loop and thus the alternator noise.
