I recently bought a used xB from a dealer. In the wallet that contains the manual and warranty information, is also an installation guide for a satellite radio (don't remember which brand). I can't tell if my car has one installed, or if the previous owner just had some documentation on installing it, in case he or she was interested in buying it. When I push the satellite radio button on the unit, nothing happens.
Can anyone tell me if there's a way to check for the presence of a satellite receiver without having to pull the stereo unit out of the dash?
