Hey Guys, I just found this site and am combing it over to find suggestions for anything and everything to do to my New Yukon. I have just purchased a White '12 Yukon SLT 4WD. The vehicle didn't come with factory Nav. and I was considering it until finding this site. I am now planning on purchasing the Kenwood DNX9990HD. Hopefully that is the first of many finds I make on this Site. After our Michigan winter passes my next purchase will be wheels. I plan on adding the Rockstar Rims with Machined finish and Black accents. Anyhow, from what I have seen so far this is a great site and I hope to use your guys knowledge repeatedly. Keep up the good work, Tony.
