Anyone with a Bluetooth Wiring Diagram?

[LukeMace]

BMW have been useless, local Indy was even more useless, so I'm going to try and attack my odd bluetooth one weekend but will need a wiring diagram to follow. Have looked over google, over the forum and not been able to find much

Basically I have all functions except sound to all speakers (pretty vital really!)

If you have a link you'd make my day! (Or if you have the solution I'll throw you a party!)

AFAIK, this link has all that's available:

Look for the "TCU" via Complete Vehicle>Body>Communication

Has this ever worked, or do you have AUX or ipod connector fitted?

I never knew I had the BT installed. I've always had the telephone on the Nav Screen:

But after installing the intravee I saw you can kick the BT into pairing mode easily so I tried it, found the BT code on the module in the boot and voila it paired and works!

Telephone menu now comes up when paired:

All my contacts now sync

I can make and receive calls through the Nav unit and steering wheel BUT there is no sound through the main system and it does not it off the radio
The microphone works and there must be a small speaker in the BT module because I can faintly hear the voice on the phone if I turn the radio off and the car is stationary. But nothing through the main system. It's as if a cut off lead is out somewhere?

My thoughts are that somebody has messed around fitting aux and taken out the plug that has the BT instead of merging the pins.

When I got it there was a stray USB cable and a few other wires hanging around (no components though which they must of taken out) so what you say could of hit the nail on the head!
How do I find it to rectify or at least check?!

If this works I owe you a nice cool beverage!

I agree with srhutch, sounds like someone bodged the wiring. Check which pins on block C have wires, reference the diagram here: http://www.z4-forum.com/forum/viewtopic.php?f=2&t=42371&p=599717
