OK, here's the scoop on XM cost and installation.

There is a link for the 4 door installation. I guess the Hybrid would be considered a 4 door. It looks VERY complicated to me, and I am fairly good at wrenching.
My dealer is going to talk to the parts guy and get me the best price he can.
It is supposed to be around $1,000.00, and I can see why based on the installation!!
