Hi, can anyone tell me where to find the Audi Nokia control module in an A4
02 Avant 1.8T I'm trying to connect my siemens s55 phone to the handsfree already installed, instead of the Nokia 6091 present now. I don't want to change the sim card each time I will use the carphone.Any information, links or schematics on the Audi handsfree interface will be appreciated.
