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?
I have a SONY CDX-C5000RV car stereo (see attach) and a Wizard.
I bought an audio cable 3.5mm stereo male plug to 2xRCA male (tested and working on my home cinema system). I pluged the 2xRCA male into the BUS AUDIO IN from the picture.
What I want to do for the moment is to plug the 3.5mm plug into any audio device (iPod, laptop) and to have the sound on the car stereo, but when I try it, there is no sound.
Am I missing something? Must I add a source selector? :?: If yes, how?
Thank you for your help
the audio bus input phono sockets on a sony deck are for the cd mutichanger, and only become active when changer is selected as a source (changer must be connected for this option).
if you do have a sony changer you could then just swap the phonos over with a cd playing and get the sound from the phone.
so this means that I have to buy a cd charger?
I read on other forums that there is another way/ to buy a XA-300 Unilink™ Auxiliary input adapter but this is very expensive.
Can I fool the head unit to think there is a CD changer connected? Can I shortcut some of the pins in the BUS control plug fooling the Head unit into thinking that a changer is connected?
Found this on eBay:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5858837454
Is it possible to connect this adapter on the Bus Control In and have audio through this adaptor? I mean, can the audio pass through the Bus Control In?
You should be able to, I've heard of people doing this with their stereos recently in VW and BMWs. There was some documentation on how to make a breakout that hooks up to any regular 3.5mm headphone adapter, but the CD controls could be used to change tracks and stuff with an iPod. It was some great stuff, it keeps things hands free so you never look away from the road really.
Hi,
I've got that to in my car... As technology is improved days after days, can't see the point to get great stereo in the car... so I'd like to use it as an ampli...
Is there a way to create a "by-pass"; something like a piece of paper clic (trombonne in French) that would tell to the SONY CDX-C5000RV a charger is connected even if it is not.... or would consider the connection as a AUX in and would only display AUX to broadcast sound signal from the Jack Plug???
Cheers
HTC PDA with 3-in-1 adapter
Hi community!
I have a small problem .... I have bought this http://www.amazon.de/Original-HTC-T-Mobile-Vodafone-Smartphones/dp/B000T92QF4/ref=sr_1_12?ie=UTF8&s=ce-de&qid=1211719958&sr=8-12 adapter for my XDA Terra and everything works very well! I can listen to my music by headphones, while the PDA is charging etc
Only in my car I got problems!
I drive a Toyota Aygo (like Citron C1 or Peugeot 1001) wich has an auxiliary input on the radio! If I connect my PDA with the adapter to the aux input everything ist OK, music is played, everything normal, but once I connect electricity, through a USB car charger, I hear a very loud noise! In addition, there is still a induced noise when I accelerate ...
If I put my MD player between sound of electricity , I don't have this noise!
Can anyone help? Do you have the problem too? Can someone test this, maybe who has a radio with AuxIn? Would an other adapter help? What do you have?
I hope you can give me an answer to my questions!?
Thanks a lot!

P.S.: Here is my question in German http://www.ppc-welt.info/community/showthread.php?t=130394
well, not sure what to tell you, I have the exact same adaptor set up in my car, with audio going to the aux in on the radio, and a car usb charger for power, and the 3rd slot with a microphone for hands free phone use. Works just great in my Dodge pickup with stock radio. I can hear music or phone over the stereo speakers, and having the microphone hookup people hear me just fine, and the unit is charged the whole time. not sure, but have you tried switching the two usb ports, maybe whatever is causing the interference will go away if you switch to the 2nd usb port?
How to fix the problem..
Hello,
What you are experiencing is sometimes known as floaty ground-loop feedback. It will be especially noisy if you're using a DC->AC inverter.
The best solution is to do as the MD player does: isolate the circuits (by that, I mean isolate the audio-output from the power-input circuits)
I had this problem once, so I went to the local Radio Shack and picked up two of these (RS Part# 273-1374) - Audio Isolation Transformers, 1:1 winding. Simply wire it as follows (using a 3.5mm male & female plug to add it inline to the 3.5mm output from your 3-in-1 adapter):
Audio input (from the 3-in-1 3.5mm output):
L -> WHT on transformer 1
R -> WHT on transformer 2
G -> BLK on both transformers, connected together
Audio output (to the plug which you plug into the 3-in-1):
L -> RED on transformer 1
R -> RED on transformer 2
G -> YEL on both transformers, connected together
When I built one, it fit into a small 2.5x0.75x1.5 enclosure (including male and female 3.5mm stereo plugs) and it helped to solve the problem. Another solution might be to find (in your local electronics store) an inline audio filter.. They are pretty cheap, usually less than $10..
Hope this helps!

sounds to me like your car has a bad ground. test it out in a different car.
same for me with any HTC adaptors. When i use a cheap chinese make there is no problem
I can not believe what's happening with my new cable MHL! I have a TV with DVI input, but I've never had any problem because with a simple HDMI-DVI adapter I could always play HD video on my TV and, from the headphone, I have the audio connected to a "AUX input" of a stereo. It always worked with my laptop and my hard drive media!!
The problem is that the galaxy s2 headset turns off the sound when you plug the MHL cable. I can not hear anything on my TV!
I do not know what to do, I think has no solution. I even connected the mobile audio to my notebook's bluetooth, but when I connect the mhl cable no sound is heard again!!
Does anyone have any solution? Is there any menu to force the sound through headphones?
thanks
I think I have a solution. I Expose it to help someone having the same problem:
1 .- Buy a HDMI male to 5 RCA RGB audio video av component cable
2.- Buy a DVI-I 24+5 Male to 3 RCA RGB Female Converter Adapter
Now you have the video and audio separately using an HDMI cable
3.- Connect the RGB cable to the DVI and audio cables to your stereo
*I can not put pictures of the cables because I am a new user and the system will not let me, sorry.

Sorry, HDMI doesn't carry analog audio signals. So you are out of luck with this RCA solution.
You need to a) change your TV model, or b) use a cheap AV receiver in between the GS2 and the TV set.
Think it's impossible to work? What bad news!! I don't understand why someone sells a cable that doesn't work!
What a fool I was to believe the technical characteristics of amazon:
Gold plated HDMI to 5 RCA component video audio AV cable.
Provides high resolution up to 1080p.
High definition sound and clear image transfers.
* if you write 'HDMI Male to 5 RCA RGB Audio Video AV Component Cable' in google, is one of the first result (amazon)
Does not matter, I've only lost 6 euros (ebay).
Thanks
Anyway I don't understand why we talk about converting the image and sound in analog. There are manuals about how to open an HDMI cable and also has the red, green and blue wires inside. Just for separate cables lost the concept of "digital? Not understand...
My TV has DVI input, which is also digital. As I said before, I have an HDMI female to DVI male that works perfectly on my TV when connect my laptop and my multimedia hard drive. If I could break the adapter, it would have too a derivation of wires a pin to another, right? And it works in high definition
All I wanted to do with this cable was to extract the sound from an HDMI cable because the Galaxy S2 lost the sound of the headphone and I can not connect to the AUX input of my amp.
The HDMI digital audio signal is transmitted as a single aggregated digital stream that contains a variable number of digital channels (from 2 to 7.1 and even more).
Also in the pre-HDMI days the DVD's SD multichannel digital audio stream was transferred using a single coaxial cable (electrical) or a single optical cable, hence no separated cables for every channel.
Therefore digital channels have to be previously decoded and separated, and then converted by DACs to discrete analog signals.
No hope then to directly get from HDMI a couple of stereo analog signals to feed your stereo amplifier, you should have read all the negative user reviews of that cable on Amazon UK.
My suggestion: buy a cheap (or used) AV receiver with HDMI inputs/outputs and then connect its analog stereo monitor output to the TV auxiliary audio input (red/white RCAs or 3.5mm connector), or just use a couple of speakers connected to the AV receiver.
I was really hoping to use this phone with any normal DVI monitor and use headphones connected to the phones headphone jack. I guess this destroys that idea.
Why is it that everytime something like MHL comes along they implement it with absolutely no foresight as to how it might be used?
I think that MHL is just similar to HDMI in that respect.
So you wouldn't get analog audio output from the GS2 even if it had an HDMI instead of an MHL.
Today the manufacturers of latest cell phones expect connections only with TV sets equipped with complete digital ports (generally HDMI), not considering their products to be used with computer monitors.
BTW, DVI video-only port today is considered not suitable for full-HD audio-video material, and probably couldn't even fully support 1080p/24fps video signals.
DVI monitors support 60hz 1080p okay. Whether or not they cans support 1080p/30 or 1080p/24 purely depends on the monitor's firmware. Most monitors woudn't support 24hz but some probably support 30hz, which I think the GSII uses.
Also I didn't know HDMI out on phones did the same thing. Thanks for telling me that.
I guess it's the matter of audio routing!
Maybe someday someone could mod the kernel to handle these types of situations ;-)
Fingers crossed!
I found this app "SoundAbout" witch let you change the output
it works perfectly for me, sound on the smartphone and video on the monitor (tested on galaxy s3)

Thank you Coincoin0017. But the problem resolved itself when I installed android 4.0.4. Now the headphone output works when I plug the MHL adapter

now days they only cater for the mainstream market.
the assumption was probably everyone will only use it on a hdtv that has its own speakers.
I agree its a sad state of affairs but thats how it is I guess, I am currently trying to get sound as I am using a hdmi monitor which has no speakers.

Excellent. ... (hopefully still works on 4.3) I have the same problem with my PWD8 which is a panel so doesn't have speakers.
Is it possible to take a cable from the phones (Note 2) 3.5mm jack and put it into an AV receiver so that it uses the speakers attached to it?
Or even bluetooth sound to a separate speaker from the phone?
Sound about app useful for allowing sound to get to av receiver via rca cable
Hi Folks,
Please forgive (and link) me if this has been discussed elsewhere, but I've not been able to find much..
I'm trying to build a sort of car dock so I can charge my phone, play music and satnav through my cars head unit and maybe take calls...
I've got the charging covered by using a USB cable (with a USB OTG adapter on the end so that my phone goes into Car Dock mode when it's plugged in) and 12v-USB adapter which are both going to be hidden behind the dash and fed from a 12v accessory feed.
I can butcher a line in on my cars head-unit (VW Gamma in a mk4 Golf) and would like to feed this using the same USB-OTG cable, rather than a separate 3.5mm jack connection.
I've been able to find people who have rigged up a cable like this for other phones, connecting the L/R to the USB data lines and ground to ground to effectively provide a line-out. But I haven't been able to to get the same going with my Desire Z. I've rigged this up to my phone and it opens the car dock and charges, but still plays audio over it's external speaker as it usually would.
Does anyone know if there's a way to get my Desire Z to output audio over a USB(OTG) cable please?
Thanks in advance,

When I drove a Taxi a couple of years back I had my SGSI connected to the car stereo with a small FM transmitter. This got its power and powered my phone, through the USB port, via the cars cigarette lighter socket. Spotify supplied the music and Google maps the navigation. I did not try, but guess that a bluetooth headset would have worked if I'd had one. I should mention that the phone did discharge despite being on 'charge'! I guess constant streaming of both music and map data over a data network, full brightness and the charge to the FM transmitter was a bit much for the usb charger
