I tried pairing my iphone to my 06 750 Li and it requested a Pin to pair. I bought the car used so it must have an original pin established. Usually when you pair most bluetooth devices, when you discover the device, any code will work. Does anyone know of how maybe I can reset it, or know if there is a master pin? I'd hate to take it to the dealer and leave it all day for something I could do on my own.
