Problem with BT Phone Install - No Sound!

[Jezzieg]

Hi there,

I posted this on the BT forum, but no nearer to finding a solution to this problem - can anyone help please?

I have a 09/01 X5, with Nav, no DSP and no phone pre-wiring. I have a 5th gen bluetooth module (purchased from eBay), and the Bimmernav kit for a non pre-wired Euro car.

I have completed the install, including ELK800 amplifier supplied by Martin at Bimmernav (as have no DSP). Phone paired with no problem (Orange SPV M600) initially, including all phone book entries etc. Only problem is there is no audio (i.e. I can't hear the other party, but they can hear me).

I have tried adjusting the gain on the amplifier, but with no success. Please can anyone help / suggest what may be wrong?

I have also checked that all connections into the radio module appear to be plugged in, and have tried repairing the phone. That has succeeded in stopping the phone book from transferring to the car, and still can't hear the other party on the call.

Questions which you may be able to help with:

1 - How can I test the amplifier - i.e. what inputs / outputs should I test for with my multimeter?

2 - How can I identify if it is a ULF problem (could this cause this fault anyway?)

3 - Could this be a compatibility issue (I think this is unlikely as I have tried a Samsung E900, which pairs and transfers phonebook perfectly, but same audio problem).

Please help - this is driving me crazy!

Any help much appreciated.

Thanks,

Jeremy.

I have confirmed that I have audio present on the ELK 800 amp outputs as required. I have confirmed that this audio signal transfers to the white X400 (is this the correct term?) plug on the existing main car loom. To my mind, this suggests that the problem lies between this point and the speakers, which leads me to think either:

1 - The connection is not already made in the standard car wiring; or

2 - There is a fault with the wiring.

I have tried to test for continuity with pins 3 and 8 of the plug which incorporates the CD changer inputs to the back of the radio unit under the spare wheel - but can't find any continuity with the output from the amp, making me think there is a problem with the wiring.

Question 1: The plug incorporating the CD changer inputs to the radio (is this plug x13321 or x01037??) appears to run straight to the back of the CD player, with only 4 wires present - where are the other two which go to pins 3 and 8 for the + and - Telephone Audio Inputs (i.e. where are they supposed to join in the loom)??

Question 2: On cars with Nav, are there any other connections not made which I need to plug in (in the same way as referred to in the technical service bulletin for cars with no Nav)?

Question 3: Does anyone have a wiring diagram showing how the white X400 plug audio wires connect into the audio inputs on the radio?

Very grateful for any input anyone can give - I am sure I am not the only one who has had these problems.

Best regards,

Jeremy.
