Where is the XM Tuner located in a 2005 Malibu Max?

thanks,

The XM external module is mounted in the passenger side rear window pillar area, from the diagrams I've seen on line.

I don't know if versions of the Maxx that don't have the XM option from the factory, have the necessary wiring harness or you'd need to get one of those and run it to the sat antenna and main radio head unit.

My best guess is that the harness is in place, at least on a Maxx LT model, and all you'd need to do is connect the XM module and antenna, but that's just a guess.
