Dear UCrewx5: Thank you for your reply. I think I know what I need to do. I will order a option 644 kit and install that. My only concern was if BMW had changed any of the wiring for the new BMW assist/Bluetooth combo ompaired to the old version of BMW assist only. Also the pairing seems to be done differently in the new combo box(no pairing button). I was wondering if this would have any effect on the display seen in the dashboard and and function of the MID and therfore pose problems in replacing the new combo with the regular bluetooth. If anyone has a clue, please respond.
