The car is an 09 ( early build, late 2008 ) and is a V6 base model. Radio is the 6 cd player, XM ( U2K?). I want to install a backup camera. I see some folks have it working thru the radio's display screen, but they all seem to be the GT or GXP models. Has anyone accomplished this on a base model? If not what would be a good camera with its own display screen that works well with our dash panel. I was thinking about using the package tray, top center of the dash, for mounting a separate display. Wireless would be great.
