Hey guys I saw this initially on Moss, but they have since stopped carrying it. I just wanted you to know that I found this to be a really great product that directly wires into the head unit wiring harness with pre-fabbed harness. No splicing required. It took me under an hour to install, and would've taken less if I had ever removed the head unit before. The radio will cut audio when a call comes in, and the phones audio comes through the speakers. package includes a central unit, screen with caller id, microphone, and miscellaneous hook-up parts. An additional BMW harness is required for $13 (through the distributor I went with). I'm a big fan and it's probably been around long enough to where many of you have already heard about it, but just in case, I wanted to post on it. I got mine through Kollman Radio in Kansas City, Kansas.
