there's a pairing code that should be have been included in your manual set that you have to enter in your phone when trying to pair the phone with the bluetooth module in the car. My SonyEricsson 3G W900i pairs up fine with my bluetooth module (while my S700i didn't), I can access the phone book, read text messages as well. Now if only BMW could display chinese characters...then I'd be happier than a pig in s--t ... lol...
