I think I've read every thread on navigation install and I don't think this topic is entirely been answered for me anyway. If one wanted to make a 2007 non-bose 2LT vehicle a bose vehicle, is it possible? I would like to install a nav and rear drop down screen. Has anyone tried this or created a part number list for the items needed? Nav unit, bose amp, wiring harness from amp to radio harness, wiring harness from headunit to drop down screen, drop down screen and subwoofer. I've purchased every item I can on Ebay just about. But what I'm missing is mostly wiring harnesses if I want to keep things stock. I purchased the harness from JP Customs, but what that item really does is bypass the wiring harness for the vehicle and you have to cut back into the speaker harness. Not entirely what I wanted to do. What we need is something similar but ties back into the stock harness without cutting. I know this subject has been hashed out quite a bit and I hope this can be answered for those like me. We really need to get together and create a packaged kit for this. Hope your reading this JP. Anyway, any help would be great.

(I don't want to put down GM. But my wife's Honda is prewired for every option, not a different harnesses for each option. I guess that what frustrates me most)

Thanks

I think you're going to have a tough time accomplishing this. Unless you stumble upon a "GM Guru" that has a lot of time to do the research, and pull the parts for you. I went through a similar situation with the reverse camera. I wanted to do a "clean" factory install like yourself using all of the factory harnesses, but I ended up having to improvise here and there to make it work. On the outside it all looks and operates like it's factory, but behind the panels is a different story. I feel your frustration man, but start looking at alternatives.
