I have a 2008 with factory Bose and OnStar. I do not use, nor do I plan to use the OnStar. Aside from the Metra Double Din plastic install kit, what other modules, adapters and harnesses do I need to get in order to install the Pioneer 4000NEX that I already have. I would like everything to work as closely as possible to OEM including the steering wheel controls.

Thanks!

This page shows everything, at a minimum you'll need the antenna adapter, a C2R-GM24 interface, and the appropriate steering wheel adapter for your radio.
