I am a newbie to the forum, so Hello to everyone! My wife and I just ordered a 2008 Acadia SLT-2, with every option available in White Diamond Tricoat. My question is, I read that GMC will have a rear back-up camera available in the 2008 model. I called our salesman yesterday and inquired, he said that he was'nt sure, but that he was under the impression that it would not be available until later in the year. Does anyone have any better information. I would like this option installed before my Acadia is built!
