First, thank you to all who have contributed to this site, it's great and has answered most of my questions about the Avic line.
Have any users installed a D3 in a 2007 Buick Rainier. A local shop is going to do it for me, but of course won't do the bypass. I even asked them to leave the dash open for me and I would do it, they said it can't be done on their premises. I am not worried about the actual wiring itself, mainly having the dash look normal after I open it back up. Heck, I don't even care about DVD video while driving, I just want the full Nav and Bluetooth functionality.
