Bought all the goodies from Crutchfield. GMos adapter, steering wheel adapter, mounting kit and antennea totaling $242. Should have it on Wed an will do it that night. As listed in subject line, I have an 07 Yukon with Bose, Onstar, Rear DVD and steering wheel controls. Hopefully I can use my factory XM antennae with the new tuner and also hope I can use Rear DVD screen. Will find out once stereo is pulled. I will continue this post once everything is in and unning. Already had this unit in my last vehicle 06 F150 that I just traded on the Yukon, so n con concern on the D3 end, just a few on the vehicle end.
