That GPS antenna is magnetized to that little plate it's sitting on top of and that little black plate piece is stickied to the dash. If you apply some heat with a blow dryer or something similar it should come right off.
It very well may have been used for satellite radio or a GPS unit. Have you looked under the dash at the wire coming from the antenna and see if it goes anywhere (like aftermarket XM module which piggybacks onto factory stereo head unit)?
All the surprises my car gives me.. I've got soo many wires, and things the previous owner left.. Like this antenna, the Nokia HandsFree U-2 Unit I found behind the radio, the mic by the sunroof controls, the wire under the passenger seat... Man oh man, what did I get myself into?
