Same issues........

OS 4.2.1.73

Trying to connect to Tom Tom 720, setting up bluetooth doesn't appear to be a problem, goes through all the motions until I try to synch address book from BB then an error appears.

Bluetooth isn't connected although the blue indicator light is on, it stays on even when the TT is turned off which it shouldn't.
Only way to remove this is to disable & disconnect on both devices.

Got the BB at xmas and everything worked fine for 6 weeks!
