hello again, my X5 has all the buttons on the steering wheel and radio display face, and the mic in the overhead panel where the lights are. but i cant find let alone connect my iphone 5 via bluetooth? so will my car have this function or is it just not working? how can i check if it has bluetooth built in? When i bought the car it didn't come with a bluetooth handbook. given that the car is 9 years old i guessed that the handbook had been lost along the line somewhere if it doesnt have the bluetooth function, can i retrofit a bluetooth module? thanks
