We are planning on buying a 2008 G6 and it doesn't have XM installed but were wondering if it is still possible to get this trough GM so we don't need the ugly aftermarket unit hanging out on the dash.
It would be best to check Pontiac G6 options, but factory equipment is never a bargain. See what they can do for you at a quality stereo shop if you want a reasonable deal. The saleman might even recommend a good one.
