I plan to upgrade this to serve as instructions for anyone interested in installing the Pioneer D3 into the Solstice. I just ordered the parts and will install as they arrive (some are on back order) Here is a overview of what I plan to do for the audio system. Pics on the right are guides for how I want it to look when finally installed. Crutchfield had a great deal going on now, free backup camera and 15% off if you buy 3 pioneer items. 15% off Code 3A185
Thanks to NBCKIPP, cartmann22, Justice and all the others on here for suggestions and ideas for what works and more importantly what doesn't.
I purchased my 2007 GXP with the base stereo and NO onstar since I planned to upgrade from the beginning. So these parts will work in that application. The only difference I am aware of is using the GMOS-Lan-04 harness if you want to keep the Monsoon amp and onstar. edit (also has input for VSS wire directly on the unit)

Pioneer - AVIC D3 (Head unit)
Metra - Turbo Wires 71-2104 (wiring Harness) <-- Not needed if using GMOS-lan-03 (04) adapter
