The Parrot CK3100 turns out to be perfect - supports voice calling, syncs the address book, kills the radio when you try to dial out or when you get a call - Sa-weet! The HK drive+play totally rocks - the UI is comfortable and very responsive, the display looks great, and the sound quality is sublime (the installer spliced it straight into the FM antenna so it's not using a transmitter).

The display is clear and sleek - matches the Harman Kardon sound system that came with the BMW. To quote the Car Toys sales guy - "Rightous, dude"!
