I'm interested in installing a Pioneer X920BT in my 2007 Tahoe. I have a factory Nav unit in there now and would like to retain all usability with the backup camera, XM, and onStar. Is this possible? I'm sure there is some specific harness I have to buy to connect the Pioneer unit to the factory wires. Any idea what the harness is that I need to purchase? Thanks a lot for the help.

P.S. and if you're in the market for a factory nav unit, mine is for sale!

You will not be able to retain the factory XM tuner and maybe not the back up camera.

Crutchfield told me no on the tuner for my '08 Silverado as well.
