Have recently picked up CPO'd 05 X5 and having trouble with Bluetooth phone functionality. Tried it at the dealer and it worked fine but now I connect from cell (new Motorola SLVR) and then hit phone button on wheel and it goes into perpetual "LOADING PHONEBOOK". I didn't get telephone manual referred to in Owner's Manual and dealer asked me to bring it in which is an ordeal. Any good instructions here?
