Does anyone know if the GPS antenna for the nav system is shared by the onstar unit? I am taking my nav out and don't want to mess up the onstar.

Why are you taking your nav out? are you replacing it with an aftermarket unit?

From what I saw the nav antenna is in the dash near the defroster vents.
The onstar is the fin on the roof.

Thank you for the antenna info. I am replacing it because I want the added features that an aftermarket brings to the table, better quality sound, bluetooth, ipod connection, the list goes on....

A lot of the gps antennas are generic. Before you run wires for the new
Nav check to see if the factory nav antenna connector on the back of
The factory radio fits the aftermarket one. I never tried it but the factory
Xm antenna going to the xm tuner behind the glove box looks like the
Same connector on pioneer xm tuners. It'll be less wires around and no
external antennas if you can use the factory antennas.
