I bought my X used and assumed it did not have Bluetooth. (early 04 build X5, standard Moonroof, non-adaptive xenons) However, I just found the car came with the Bluetooth Passkey card and bluetooth information. Does this mean I actually might have it? There is no cradle in the armrest, and the only send/recieve button I have is on the steering wheel. How can I confirm I do or don;t have BT module?

Assuming I have BT, can I use the steering wheel key to put the car into pair mode?
