Just a quick note: I just bought a Motorola Razr V3 and it is fully functional with my car. But, not until the latest software update was made by my dealer today. Apparently some cars are getting through without this update and you will NOT be able to pair your phone. So if you have such a problem don't just assume it's a phone problem, your car may not have the latest software updates. These are coming through apparently with some regularity.
Happy Bimmering!!
