I think I have it but I am not 100% certain.

if you have a MULF2 with professional radio/idrive installed in your car, you should be able to do the retrofit even without the factory wiring.

In my car, I had the MULF2 and professional radio without any wiring. So i had to add the mic wiring myself and just connected the bluetooth antenna with short cable in the trunk.
