BMW F30 Microphone issue

Hi guys,

I was helping a mate out installing a HU_Entrynav business navigation headunit in his car. His car is a 2012 F30 - 316D ..

Previously it had no center USB, no navigation, no bluetooth or anything... Combox is not present either.

So i did the retrofit for him, did a bit of coding - not much though. Just made the new display work etc...

Enhanced bluetooth works - music streaming and calling
navigation works perfectly.
center usb works too.

problem is the microphone doesn't work.

Now for the navigation to work properly i had to use an emulator, which means there's a harness between the OEM quadlock and the headunit. i installed the wires for the microphone in pin 22 and 17 on the oem quadlock as i figured all the others wires were going directly into the oem quadlock and signal was passed through the emulator harness into the headunit ..

So my question is:

what did i do wrong? is it just a matter of coding? i did code a few things on the microphone part after having read through some online forums including this one.

coding for the microphone is as below:

MICROPHONE_POSITION: wert_01 (Ceiling)
MICROPHONE_PARAMETER: wert_01 (not sure what this does)
MICROPHONE_NUMBER: wert_1 (single microphone)
MICROPHONE_SENSITIVITY: L4_mic
REFERENCE_CHANNEL_TEL: aktiv
REFERENCE_CHANNEL_TEL_MODE: wert_01


Please help me

Well that's good advice ! Thanks so much!

Will try to swap them

Any good advice on how to get the wire out of the quad lock ?
