Good Luck! I have an 05 that I am not sure if it is bluetooth or not, I tried a Blackberry and my LGenv3 and my phone finds the car and I put in the passkey and it won't pair. The dealer I go to is useless, they replaced the bluetooth module but it still does not work. I am in the process of complaining the the owner and BMWNA to fix it.

Anyway back to OP, you need to get the passkey from a dealer, they get it from the module itself or they can get it from the car readout from the key.
