BerryReview just pointed us to a handy application from RIM for an incredibly small sect of BlackBerry users: those who own a Land Rover LR2, Volvo S80 and V70 or Jaguar XK. This application, the Bluetooth Pairing Helper, supposedly eases the Bluetooth pairing process with your car as outlined in RIM’s knowledgebase. Outside of working with a microphone built into the car for voice calls, what other applications are there for Bluetooth in your ride? Music? Maybe some diagnostics?
