Hi i have just bought a a3 54 plate and have conected my iphone 4 via bluetooth. the calling works fine but i cant find any way to transfer my phonebook and have to scroll through my phone to make a call rather than doing it through the nav plus. the car has a cradle looking thing fitted on the dash but i dont want to pay over a hundred pound for the correct cradle when i can just use the bluetooth. is there something im doing wrong? any help would be appreciated thanks
