My bad.
You were talking about the backup camera with the display in the auto-diming mirror, correct? Yes. There is a kit, and it has been done by individuals. (I thought you are talking about the kinds with display in the center dash.) The instructions are quite long (about 30 pages if I recall correctly).
Pre-wired? Definitely no for pre-2010 model, but not sure about 2010.
If not pre-wired, you need to pull lots of penals off.
As long as you are experienced, you can allot an afternoon to do it.
It's a good advice to read the instructions (PDF) first before you buy it.
Don't bother with it. I had it on my wife's 08 GT and it was too small to be usable. The one on her 2010 screen on the console Bose stereo is much better.
I agree that the Navi screen is a bigger/better picture but if you don't have that option the screen in the rear view mirror is certainly adequate. I would definitely rather have it than not. The view out the back of this car (especially low to the ground) is very limited...even the small image helps a lot.

2010 models with the Bose stereo option (no nav) comes with the back up camera screen. You do not have to get nav to have back up screen in console for 2010. The Bose stereo comes with an LCD screen that's also used for the back up camera. I've mentioned this a few times already in previous posts. You need to go to a dealer to look at one.
