  For other BMW models you might use a different adapter cable, (both BMW harnesses are labeled "E46". The only sure way to tell them apart is to look at the pins on the car side connector -opposite end from the one red and one black plug end. The one for the Z3 has a set of rounded pins. The other one has bladed pins.) You would use the diversity antenna adapter if you have a diversity antenna and you might need a trim kit if your stock radio is a different size.
