I have seen this question in the archives, but without a good answer. Is it possible to connect a non-BMW handheld cellular phone to the in-car wiring to make use of the rooftop antenna and built in speakerphone capabilities? If so, which phones work, and how is it done? My E46 is on its way and I need to buy a new phone.
