connect original car Bluetooth to Head unit - MTCB Hardware Development

Hi my friends, today I need your help...
my car (audi a3) is complete of OEM's bluetooth handfree with audio quality more better of HU bluetooth...
my question are, is possible to connect oem audio to HU to aux in???
NOW if I use original oem bt all work fine ,but i can't hear voice incoming, maybe miss a connection from oem bt to HU
i link the original electric scheme...i found a way to bring voice call from original bt and connect to HU aux in....
thanks in advance

anyone help me.....
I try to connect original audi sound output to HU audio input (rca) (like a photo below), but i ear only a noise.... can't find the audio signal of original audi bluethoot... any ideas my friends?

I would be interested to know if this can be done.

i have same problem
know you whic is the mute connector
in the our head units?

I solved the first part of problem:
In the picture below can see the original electric scheme of original Audi radio (concert III) , there are 2 pin "tel+" and "tel-" ... Simply connect tel+ to hu audio in left and tel- to audio in right.... All work!!!!!
Now the problem are
1- can I use the "mute " cable ( from original Audi connector ) to switch HU to avin when there are a call incoming??
2- the " mode" button on my steering wheel at the same time switch input from HU and conctacs from Audi oem Bluetooth.... Can I change the mode button with another button (example the voice command button now is unused in my steering wheel...) ??
Is very important to find a fast way to switch HU to AVIN when there are a call incoming!!!
Thanks

The button "voice command" are assigned to Bluetooth by mcu...
I could change it to AV IN... but the mtc keys don't work...
I have write in the script file:
App_69=com.microntek.avin
But nothing
Any ideas???

Sorry to resurrect a very old post, I'm sure the OP has long since changed his vehicle but it may be of use to some current owners.
A much simpler and logical solution would be to use a Parrot SOT cable and splice in the Tel+, Tel-, plus Mute cables from the redundant red 10 pin ISO Audi connector, since these work in the same way and you would get full muting and call audio without any app switching.
It is probably best to code out the Audi lady voice activation with VCDS. If you use Android Auto Google Assistant should work to place the call better. You get the added benefit of full DIS display (for phone only) and answer/hang up on the steering wheel too. Whether the bluetooth quality is better I am not sure, since these Audi bluetooth phone preps are pretty old now - I have the full prep in my car and before I installed an Xtrons I remember it working well with good call quality but the lady didn't hear too good at times.

Bluetooth stereo review

Having had so much help from this forum and being a non programmer thought I would try to give something back.
Recently bought the Sony MEX BT5000 car stereo. The install was really easy. I bought a cable to convert from my existing pre installed car stereo to a standard iso fitting. It is then just a matter of plugging the cables in and replacing the stereo. Due to the integrated bluetooth no problems with having to tap into speaker cables to mute the radio for calls.
I also ran a standard red/white phono cable from the back of my stereo via the AUX IN connection to plug into my MP3 player. The stereo has built in A2DP if you wanted to stream via bluetooth on your phone.
Call quality appears to be very good in both directions, no complaints so far. The mic is built into the stereo with no option on an external one. This did slightly concern me before buying but all is well. I had done some research and some people had experienced problems. I think this is due to the position of your stereo. mine is high up in the centre console. If yours is at the bottom you may experience problems.
There is no "talk" button similar to a earpiece. On pressing the talk button you get various dialing options to use presets, phonebook or dial a number. If you want to use Voice Command you just press the button on the phone and then it transfers the call to the stereo when it starts dialing. To receive a call just press the button on the strereo or set it to autoanswer.
Tom Tom works with no problems. All instructions come out the phone though if a call is received it will mute Tom Tom. I like it working this way as I wouldn't want TT to keep interrupting the stereo. It could be possible to make it work through the speakers but I haven't tried.
Stereo sound is good but I am no audiophile. It is way better than the standard stereo that was in the car before.
In all I would recommend it. Easy install with no messy wires involved and easy to pull out and transfer to my next car when required. most importantly the call quality is good.
Only downside would be the lack of "headpeice" talk button but the workaround works well. (I did read on xda somewhere somebody had it work that when using voice command after pressing the phone button the notification messages went straight to the speakers and used the stereo mic. after installing a cab upgrade this stopped working. I may try re-installing VC to see if I can get this to work.)
To install to the stereo phonebook uses a bluetooth transfer. haven't worked out how to this yet as only IR transfer seems to be allowed from the phone. Obviously using VC this doesn't really matter.
I just installed the MEX BT5000 in my car, too. My experiences with the BT phone are roughly the same as yours -- the mic works really well, considering it's hidden behind the faceplate.
I've gotten the phonebook transfer to work. Just select the contact, then tap Menu/Beam Contact. It'll try IR first, then Bluetooth. I have the Sim Access Profile (SAP) hack installed -- that may be the factor here.
The one issue with phonebook transfer is that the phone numbers don't display properly on the Sony -- I just see +1 with no areacode/phone number. The numbers dial properly, however.

Philips SBH6100 BT h/set and Voice Command 1.6

I am getting a strange effect using the above combo, and was wondering if anyone has any thoughts:
I am using the Philips SBH6102 which I would definitely recommend to anyone, having used others such as the Sonorix OBH-100 (plasticy, poor mic. quality), IOGear (good quality sound but poor mic, too big on the ears, neck band broke v. easily), and some black triangular ones whose name I forget but I broke trying to put them into a nicer pair of earphones
Anyway, that's all in the past. I am now using the excellent Schap's WM6 Pro 4.00 RC ROM (much praise for this excellent ROM) with MS Voice Command 1.6. When I pair the headset and apply both the wireless stereo and handsfree profiles all is good, apart from one thing...
When I press the voice dial button on the Hermes I get voice command through the headphones, and I use the built in mic to give the command. However, I can also trigger voice dialling by pressing the Back control on the headphones, but then the _phone_ speaker responds and I have to use the phone mic to speak the commands.
Obviously I would like to press the Back control on the headphones and use that to respond, as I can then leave the phone in my bag - or more importantly connected up to some power as with BT on the battery drains like there was a hole in the bottom of it, but maybe that's for another post.
P.S. the SBH6102 comes with a 3.5" dongle that auto-pairs with the headset when they are both in discover mode - this is an excellent feature when your son wants to borrow the headphones for his iPod, so I wouldn't recommend it
In other words you can't initiate VC from the headset button? Thats pretty much a problem with MS VC.. Use the updated .cab located in this post..Its the 3rd post down.

bluetooth sound issues

it has been discussed before but I still can't get it.
I do have sound via bluetooth in my car when answering a call or initiating a new one.
but I can't hear anything from the phone applications like navigation or musicplayer.
how can I change that?
It has nothing to do with the bluetooth kit in my car as a blackberry worked seamlessly with playing music via BT. Even my old HP ipaq 514 also made sound announcements through BT.
Any settings to adjust?
You must change a bluetooth-setting.
- Comm Manager
- Settings (right button)
- 2 Bluetooth
- 1 Bluetooth
- select your BT car-stereo from the list (don't click)
- Menu (right button)
- 4 ... wireless stereo ... (don't know the English name, in Dutch "Als draadloos stereo instellen")
In my experience, each time you reconnect the device, you have to do this again because it automatically resets to the handsfree setting.
thanks! sounds promising.
but it doesn#t work as expected. the phone is either a BT headset or a BT stereo. not booth at once. hmmm not sooo good
Ok but this will only work if the car supports A2DP, correct? Because I have a BMW and when it is connected that option is not there. The BMW bluetooth module supports just headset profile.
But if I use a normal bluetooth headset I can actually get regular audio out of it some times. The car strictly works with phone calls. Perhaps sometimes audio is sent to it but ignored, I mean it can transfer phone numbers (dial in car screen), phone book so of course it should know how to tell if it is in a call or not?
the features you describe are part of the rSAP bluetooth profile, where actually the car is the phone and only borrows its identity from the phone. totally different story.
so if you do a call actually the car holds the connection to the network. Your phone is only involved as kind of remote sim-card reader.

Very strange SGS3 headset problem

There goes my first pos heret:
Recently I have bought an international SGS3 branded by T-Mobile and it is currently running I9300XXBLFB (ICS 4.04). Some time before that I have also bought a Belkin headphone adapter. What it does is that it basically provides a microphone and a standard 3.5mm jack port for the headphones of your choice. It also has a small 3button Apple like remote (answering button and +/- loudness controls). Good idea for someone who loves his headphones, which don't come with a microphone. It also comes with a TRRS ending typical for Apple.
The adapter worked ok on my Samsung wave with a TRRS switch (loudness control of course didn't work at all, but answering did; loudness doesn't usually work on anything but iCrap). It also seemed to work on my SGS3 at first, but without the switch (TRRS layout is the same as in Apple).
When plugged in I get a notification that headset is recognized, when I make a call the microphone works, headphones work and the answering button is able to stop the phone call. When not in a phone call the answering button starts and stops the music player, so again kind of a standard behaviour.
Now the fun part starts when I answer a phone call with the answering button. The call gets picked up BUT the headphone icon at the notification disappears (behaves like the headphones would get unplugged) and the microphone in the headset doesn't work anymore. I also am not able to drop the call and after I drop it with the phone itself the music switch via the headset doesn't work. Detaching and attaching the headset via the 3.5mm port again gives the headset icon back.
I compared it with two other headsets: stock and Thermaltake Isurus headset.
Both of them behave correctly when I answer a phone call. Both remotes work correctly as well, I am able to pickup and drop calls and the headset icon stays where it should.
Anyone has any ideas what may be wrong with the Belkin headset adapter? Or why SGS3 behaves so strangely with this accessory in particular? Anyone encountered this before?

Bluetooth audio in car

Hello,
I was wondering if maybe someone experiences the same or if someone has a solution for this.
When I drive I like to use TomTom Go on my phone as my main navigation, I don't like the car's navigation. I have a new Peugeot 308 SW and it has a large multimedia touch screen.
I enable bluetooth on my phone so that when I am called, the audio of the call goes through the car's audio system. This works great but because I am using bluetooth, the audio from the navigation is muted. Looks like the audio via bluetooth of TomTom Go (but also Google Maps) cannot communicate with my car's audio system. This is really annoying and the only way to get audio from TomTom Go is to disable the bluetooth and then I get audio through the phone's speaker, which is fine.
I tried an app called SoundAbout for Android and this gave me the option to route "media audio" via speaker. So I thought that I had found the solution, unfortunately it also routed phone call's audio through the speaker.
So, to summarize: does someone have an idea how I can enable bluetooth in my phone, use a navigation app (like TomTom Go) and hear the navigation's audio? I am fine if the audio is then through the phone's speaker, as long as the phone calls are through the car's audio.
Thanks for the help and Merry Christmas!

Hi,
I've checked all the settings, in TomTom, Google Maps and Bluetooth, nothing helps.
I've been reading some stuff online and it's a very common issue. I do read that people using an iPhone don't seem to have this issue.
In Google Maps' settings I've checked that audio goes through Bluetooth, but no success. I guess it also has to do with the software in my car. My colleagues have the same problem. I guess when I use TomTom and I want to hear turn-by-turn guidance, I will need to switch off Bluetooth.
I will keep looking for a solution and will reply here when I find it. I just installed A2DP Volume Androi app but haven't test it yet. The description sounds promising, I hope this helps me.
You can try different navigators, like igo,that can use alarm volume setting instead of app volume setting, and it can be seen by Bluetooth speaker

Thanks PeppeBove.
I have Google Maps, TomTom Go and Sygic, not really looking for another navigation app.
I will keep looking for a decent solution.
Thanks for your input!
What is your car audio system? If it's Sony's, you can use Songpal.
you can hear voice from phone through your car audio if you change input from radio to bluetooth.
#1 Set up can be:
CAR
Input: bluetooth
PHONE
play music by bluetooth,
use your navi, and music will automatically go quieter when navi speaks
#2 Another solution is:
PHONE
in app, in voice settings or bluetooth settings, set up "use phone speaker instead of bluetooth"
It will play navi by phone, and calls will be like always by car system.
You cannot mix inputs in car system, so radio and phone bluetooth. When you have call, your car system is changing inputs, but it take some time. So if you would like to play it like that, you will have 3 sec of every communicate cuted off. So better use, solution #1 or #2
