I have a 645Ci convertable with a Nokia 3660.It does very weird things that I think are a function of the BMW, and not of the Phone. It "decides" when it wants to connect or not. when it is connected it works fine. It sometimes gives me the "connected" display, but it does not connect. Anything short of a reboot of either the phone or the car computer will not make it connect.It is a great feature when its working, which is 80% of the time. But I expect more out of BMW AND Nokia. By the way, the I entire I-DRIVE system has issues. I think they need to strip more layers away, and make it more basic. it is way too complicated and not at all intuitive. My Lexus LX-470 has a touch screen navigation display that is FLAWLESS. ARE YOU LISTENING BMW?
