Anybody know where I can get the Phone wiring diagrams for a 1997 528i. I want to remove the analog Motorolla phone and install a hands free CellPort VR kit in the OE console location using as much of the OE wiring as possible. Radio interupt, microphone, etc. I understand that the old analog and new digital are not compatible, but I would like to run as little wiring as possible for the new hook up. Thanks for the help
