Hello. I just bought a 335i with the sat prep, but no receiver. I'm getting quotes of $600-900 to install and program it, and had a question or two. I called the dealer to make sure the part number you list will work on my car, and the parts guy got very protective of their monopoly, and gave me a line about liability and everything, then told me the unit has to be programmed for the car, and once programmed it can't be reprogrammed for another car. I know most of the time the parts guys don't know what the service guys know or do, but I just wanted to make sure I can use a previously programmed part (if that's even true) for my car. I know the car has to be programmed, but does the receiver? If it will work, is it still for sale? Thanks.
