Thank you for precious answers,
the real problem is that nothing apper after turn the key and pressing the R/T button! no messages on car's computer or display
I tried to pair:
nokia 6310 (correct sw version)
nokia 6600
blackberry 7100
sony v800
all the mobile phone recognized the BT on bmw (BMWxxxxx) and only the phone ask me the BT passkey, after that all the mobile phone are not visibile on the computer's car.
Again, all the answer will be appreciate.
