XDA CarKit Wiring

Hola!
I'm trying to work out how to make my own XDA car kit cable. I have the pinout for the XDA - thanks to the XDA Developers Site
- http://wiki.xda-developers.com/wiki/Connectors
I also Have a pinout for the back of my Stereo (Philips CAR 400 From a Vauxhall Astra - '02) thanks to
- http://carradio.hit.bg/philips.htm
I have done some preliminary testing with small cables and connectors that go into a standard phono input on my big stereo in my room and have been successful at making a mini-kit, but am having real trouble working out what the pins on the back of the car stereo do (i.e which is for audio input from the phone)
Labels are as follows:
PHILIPS CAR400
01 - SVD
02 - SAC
03 - SCL
04 - Tel. Mute
05 - TIS
06 - Batt. +
07 - MRQ
08 - Power Antenna
09 - DDL
10 - Lights
11 - ACC ( 12 v + )
12 - GND
13 - SDA
The only one that make any sense is Tel. Mute (Anyone any idea what voltage I have to put accross this to get the system to mute)
If anyone knows what the rest of the pins stand for your help would be much appreciated.
Many thanks,
Will

You put the mute to earth to mute the stereo - normally it's floating.

1 down
Good good, one down, 12 to go.

Now I've read your question.
Answer is probably none of them. All the mute does is silence the audio (and pause the CD on some radios) - the assumption is either that you have a remote speaker for the phone or you use some commercial adapter like Autoleads to intercept the output to the car speakers via a relay. Autoleads sell a huge range of car/stereo specific leads that all provide a "generic" phone interface for Nokia phones. There are also a number of patch leads that enable you to plug specific car kits to the Nokia interface (which is just Battery, switched +, ground and mute with a 3.5mm jack for mono audio. Most knowledgeable guy for this stuff is Terry White on http://www.siocommunications.co.uk/ (he'll sell you the appropriate leads or make up what you need).
Note that the Autoleads solution (which mutes the stereo and uses relays to swich the audio from the phone to front speakers) renders the stereo automute unnecessary, but it is nice to pause the CD anyway and usually you get a front panel indication of phone call which is useful.
I note that the Philips connector also has an audio L/R/Gnd input. This is probably for an aux source like an MP3 player (eg XDA) but of course this needs to be selected on the radio and will also be muted when the mute pin goes to ground.
Hope that helps

I guess the other pins are things like CANBus, D2B wakeup etc. a bit like Siemens/Bosch

Last one. The Autolead you need is 06-078B - £47 + pp from Terry.

Phew!
That's a mighty big cable?
I notice that it has a 'big connector' (I've marked it in yellow on the image I've attached with this post). There is already one of these on the existing setup. This wouldn't mean I have to completely rip out all of the existing wiring would it?
Also, the jack (Red on the image) looks like a mono jack, I assume this is the bit that plugs into the phone or which I can adapt to plug into the phone?
Seems a bit expensive too, is it really necessary? Can I just forget the auto mute feature and have the phone output go through the 'MP3 In' inputs? That way I can listen to the music on the XDA through the car stereo as well as any sat-nav stuff I decide to install later on.
The main aim of my question is to try to develop a cheap solution to an XDA-Car audio interface. Do none of the connections on the back of my stereo allow me to wire in some sort of auxiliary input?

Yes it is big but it does the job and you can usually find room.
The connector(s) go in line with the ISO and stereo specific plugs, so routing all the power and speaker outputs via the relay module. You don't rip anything out, or need to break into existing wiring, so you reduce risk of problems or warranty issues - it really is the lowest hassle solution.
Yes the red plug is the phone audio input and is designed for Nokia kits.
Expensive? Not really, considering you avoid any hassles and can remove the kit after with no changes or damage to the car wiring. Replacing connectors and fixing car wiring can be expensive.
Yes you could go into the Philips cnnector from the XDA, but you would have to manually select Aux in on the radio, and it wouldn't mute anything. If you were listening to the car radio you'd need to answer the phone and also switch to aux in on the radio to hear anything. Sounds a mess to me!

OK
Ok, so assuming I use the new connector to wire in the phone and have it working through a seperate speaker, how do I connect the MP3 Outputs of the XDA into the stereo. I have no problem using a seperate speaker for the voice on the XDA but I really want to play the XDA music through the Car's built in speakers.
I understand I'll have to come up with some way of getting the sound from the XDA to the speaker AND the car stereo but I don't mind that, It's just something I'll have to worry about.
Most car stereos I've seen have a seperate set of Phono Sockets for auxiliary inputs but this philips doesn't. What do the pins on the back actually stand for in english? (Laymans terms please because I don't understand the long names but I will be able to fathom how to use them if you tell me what they actually do, long names might be ok too cos I can always look on Google to find out what the various bits do.)

Actually I screwed up - looking again at that wierd Bulgarian* site the CAR 400 looks like it has the 26 pin connector and the phone lead would be Autolead 06-053B.
http://www.siocommunications.co.uk/06-053B.html
Also it looks as though the CAR400 does NOT support Aux in - sorry about that - although you could try putting signals onto pins 9 and 10 (using 3 as Ground) and see what happens (that's what the CAR660 uses). No warranty actual or implied!!
* This guy is promoting software to crack EEPROM codes on car radios and to clock cars with digital instrument clusters. Not sure I'd be so keen to build a close relationship there mate!!

No Fear
Thanks anyway, I've got a few exams to sit this coming week so no chance to fiddle for a bit but I'll post back again once I work out how it goes. Looks like I'll have to find some sort of seperate amp and patch it in somewhere to output to the car speakers.
No connection between me and the Bulgarian bloke, just found the site on google as a means of showing you the pinout on the back of the CAR 400.
I'm assuming Pins 9 and 10 CDR and CDL stand for CD - Left and CD - Right respectively?
One last quickie before I go, can I source ISO connectors (Just the plastic bits) from anywhere so I can maybe make a patch through cable? I'd need a male and a female one.
i.e.
CAR STEREO (FEMALE ISO) ---> Wiring (MALE ISO)
becomes
CAR STEREO (FEMALE ISO) ---> NEW MALE ISO --------> MY STUFF ---------> NEW FEMALE ISO ---> Wiring (MALE ISO)
Cheers for the help, I'll have a mess about over the next few weeks and post back with my results in case anyone's interested.

Just a note to say I've found some ISO Connectors. You can get them from maplin.
http://www.maplin.co.uk
codes
QK25C (headunit end) @ £4.99
MZ76H (car end) @ £6.99
Anyone finds them a bit cheaper let me know...

Another quick note. I've found a small amplifier from Maplin (Code N67AW) 40W 6-16V. (MONO ONLY)
The instructions say it is a 'bridge type' amplifier and that the speaker connections should therefore not be to ground (As in a car).
The setup works fine on my test rig at home, but I was wondering, will I just get lots of noise if I connect it up in the car, or will I blow everything up?
So far my plan is to make a patch through cable that amplifies the XDA signal direct to the car speakers and has some form of automatic switch to detect if audio is coming through the XDA. If it is, then it mutes the signal from the car stereo and patches the XDA through.
Any suggetsions?

Blue Angel audio connector?

Hi,
I want to connect an external speaker and microphone to my Qtek9090. I thought the easiest way to do it is to simply cut the headset wire, plug the 2.5mm connector in and connect my speaker and mic to those wires. I have taken apart the headset that comes with it and there's the following wires in it:
wire1:
- blue
- copper(1)
- red
- red/green
wire2:
- white
- copper(2)
From taking apart the volume slider I think blue and copper(1) are the wires for the audio (L&R). But I'm not sure. I can't figure out what the mic and ground wires are :?
Does anyone know more? Anyone tried looking at this?
Grtz,
DUTCH

just feed a low level audio signal to the wires. You should distinguish left and right. The remaining one must be the mic....

or...
buy an adapter. Both expansys and proporta.com sell adapters.
Nigel

I've been searching for those adapters and found many. The only problem is: none of them have a microphone connector :? .
Now I might have an option here, but i'm not sure this one suits the Qtek9090 (Blue Angel) I have: if I use this one. I could connect my speakers to the stereo 3.5mm headphone jack and my microphone to the mono 3.5mm headset jack.
The only thing is: what part of the headset connector is the microphone? The tip?
Grtz,
DUTCH

Blue Angle Plug
Tip Mic +
Band 1 Audio Right +
Band 2 Audio Left +
Base Common Earth (-)
Headset Lead
Wire 1
White Mic +
Shield Mic -
Wire 2
Red Audio Right +
Red/Green trace Audio Left +
Plain copper Earth (-)
Blue Earth (-)
NOTE
This is not the same as it was on the Himalaya.
Therefore no adapter or headset made for the Himalaya will work with the Blue Angle.

Do you know if it's compatible with nokia headset ?
like this one :
Nokia HDD1 : http://www.nokia.com/cda13/0,5184,733,00.html
bye
Emanuele

No, I've tried with a Nokia wired headset and it didn't work at all.

I ordered the audio connector mentioned (this one).
When recording a note for example everything works just fine, BUT when in 'phone mode' (making a phone call) it doesn't work.
Anyone got a clue/solution for this? Or should I start thinking about making this work via the 22-pin connector?
Grtz,
DUTCH

9090 should support audio from the bottom connector. I assume you want to use it in your car. If you want to connect a external speaker you should amplify the signal. There is a DIY carkit on http://wiki.xda-developers.com/wiki/Connectors . Maybe this could be handy. Also my phone supplier told me that in about a week there will be a complete carkit WITH decent Carcomm cradle and GPS connection (all wired so no BT connections needed). I will buy this when it is released so will keep you guys updated.

if I use this one. I could connect my speakers to the stereo 3.5mm headphone jack and my microphone to the mono 3.5mm headset jack.

I purchased this one for my old TMobile xda I and the Blue Angel.
Both are headphone jacks and niether cna be used for a mic. There is a built in mic and mute button (that you have to hold)
Raptor

Here's the headset pinout + Where's tha audio in the bottom?

I used to have the original XDA (T-Mobile USA). I just bought the Cingular-branded Blue Angel (btw, they come unlocked).
As many have stated, the pinout for the headset is different. Here's how it's set up in the Blue Angel:
Sleeve - Ring 1 - Ring 2 - Tip
Ground - Out R - Out L - Mic In
As opposed to the original XDA:
Sleeve - Ring 1 - Ring 2 - Tip
Ground - Mic In - Out R - Out L
Now, I really need help to find the Audio in/out pins in the bottom connector. As far as I know (I checked), pin 1 is no longer Mic In.
Also, grounding pin 19 does not turn off the internal mic and speaker.
I'm a pro journalist - In the old XDA, the Mic In in the bottom connector gave me amazing sound from a Shure Microphone (through custom made cable with a line matching transformer).
I desperately need to know where's the Mic in and Audio Ground in the bottom connector. The Mic In in the top headset connector doesn't provide clean sound.
Thanks everyone.

Hey Uspino,
I got the same problem. But i find out that the pinout for only the audio on the bottom is the same as on this page :
http://wiki.xda-developers.com/wiki/Connectors
I hope anybody can find out wich pin is the mic. This weekend i will try out, so maybe monday i have an answer.
Pin 12 builds up a voltage of 3V to 4V when you make a call.
BTW, do you have a loose 22-pins connector for the mdaIII and can you tell me where i can buy this? Now i take the connector wich is shiped with the MDA for charging. I confirm the pinout you find out for the top headset.
Thanks anyway!

How to make our own Headset to use with Universal

Anyone interested in this topic to advice to make our own Headset

Count me in
I would be interested. The headset supplied is not very good: the earpieces don't stay in place to get the best sound and the wires are to 'wirey', ie they're not soft enough, and they don't lay straight.
I had seen before someone had taken the Nokia hands-free headphones (similar to the Universals, with a central piece with a mic and button on) and they manages to fit a tiny 2.5mm stereo socket in it, so any standard headphones would plug in. But on the Universals, I don't think there's room.

www.remtrak.com sell 4-way Jack Plugs (3.5MM Angled or Straight) so we could feasibly manufacture our own, with the corrct pin out.
L, R, GND, Mic - But which is which?!
I have an old 80's BT Viscount Handset removed from it's phone base and itching for headset duties. . .

I don't see how that helps me hook up a Pokia, Novophone, or connect my own home-made devices. But good link for Non-Geeks!

Mini USB > 3.5 Jack?

Any adaptors that will allow me to use proper 3.5 inch headphone jack in place of the mini USB ones ( i dont like the in ear phones) checked ebay and couldnt see anything?

you want get one of these http://www.expansys.com/p.aspx?i=142090 - Mike

Ouch, that thing is both horribly badly designed and prohibitively expensive- it's going to stick out what looks like an inch by itself, most headphone plugs will add another inch on top of that- I need something that fits flush with the bottom of the phone (comes out at a right angle) AND supplies an input for the charger. One can only dream!
The orbit would make a great on-mains Wifi internet radio if such a gubbin existed- hook up some speakers, start TCPMP, sorted!

in which case if you don't like wires stop messing around and get a set of A2DP compatible headphones - the quality is very good, but far more costly than a cable addaptor - the choice is yours - Mike

Might have been worth while if I didn't use an iPod for all my portable audio needs- have you seen any A2DP compatible speakers around?
Looks like there are hacks out there, but no official products, the combination really would just turn the Orbit into an incredibly expensive Wifi radio! But where's the fun in just going out and buying a proper one!

Have a look at the products made by Parrot there are a few Bluetooth audio add on boxes, I fail to see the relevance to WiFi?? as the A2DP profile is Bluetooth - it even works on the T-Mobile MDA-CIII which has no WiFi - Mike

I say wifi radio because I listen to internet radio stations around the house using the Orbit, and the ol' tinternet comes via the wifi doohickey!
A2DP is, of course, a bluetooth profile and would be the method over which I get decent sounding audio from the Orbit to some speakers whilst still having the Orbit plugged into mains so the battery doesn't get sucked dry... that said I think the Orbit will last a good few hours streaming internet radio, although I have yet to put that to the test.
My other solution would be, as mentioned above, an adaptor that allows both the charger AND headset to be plugged in- I can't see this as being technically impossible.
With a brief cursory investigation I have discovered, I think, that the headset uses a proprietary 6-pin connection on the opposite side of the mini-usb connector. The headphones do not use the 4-pin standard mini-usb connector on the other side, but a connector that uses both should be reasonably simple to produce. Ergo it should be childs play for a third party to produce an Artemis dock that contains not only a connection to USB but a standard 3.5mm amplified microphone socket alongside a standard 3.5mm amplified stero audio jack... not to mention a button on the front of the dock for picking up calls and a volume slider if you really wanted them.
Call me crazy, but I want one of those!

You could try this
http://www.expansys.com/htc/p_htc_item.aspx?i=145066
Might do the trick even if it is a bit long
Rich

Dear lord! You've made my day! Hmmm, a little jiggery pokery and I might even be able to incorporate that into a dock but it'll be fantastic for charging and listening to net radio at work- takes that little extra load off my desktop PC.
Cheers!

Glad I could help

Hi,
Does anyone know if the above would work with a set of mini stereo speakers with a 3.5mm headphone jack (like the walkman speakers i used to have, back in the day...) to listen to the FM radio while charging the phone from mains? Or would you still need the headphones plugged into get any FM reception?
Daft question maybe, but I wondered whether the device would just use the speaker wires as an antenna instead of the headphone wires?

It will work fine, I am going to use mine to connect my orbit to my home stereo and charge it at the same time.

2.5mm 3 pole jack plug
Hi,
Anybody know of an Artemis mini usb to 2.5mm 3 pole jack plug adapter which allows the connection to deliver audio and microphone capability ?
I would like to connet my Artemis/Orbit to the Autocom intercom system on my motorcycle . This uses a lead with a 2.5mm jack plug at the phone end and a 3.5mm jack at the Autocom system end. Both are 3 pole.
Thanks
P.S. hope you don't mind me jumping in your postings

try doing a search for "2.5mm"

A very good Items for the Artemis on EbaY :

Is this so you can listen to music from the Orbit? I've had difficulty on my bike with this...music cuts out and wont restart after phone call is over. In the end, I bought the Autocom bluetooth dongle and now bluetooth the Orbit to the bike. I get phone calls and GPS just fine, but I use a wired iPod for music.

Does this support the Artemis? It isn't in the list....

There was a posting for the mini USB PinOut some Time ago. Look in the wiki Section to find it. Here is what they showed up with.
Maybe This will Help someone to build their own Adapter or whatsoever.
Greetings
Jabami

so what was the general concensus with using Autocom? Did the 2.5mm jack work?
I want to avoid using the bluetooth option on autocom, since I might just as well go for a Scala bluetooth headset instead if the jack doesnt work...
