I'm having further issues with the Bluetooth stack. On the 730, I had no issues transferring the phonebook to my car. Now, no dice. Further, I cannot "End Call" through the bluetooth interface in the car. I can receive and make calls (if I dial or through the handset, since there is no phonebook now), but cannot hang up. This is awful. If it had been an issue with this car and the 730, I'd be patient, but these issues are a definite step backwards.
