GMC's overhead camera is a great feature that allows drivers to see what's behind them when backing up. The camera is located in the center of the rear view mirror, and it has a wide-angle lens that gives drivers a clear view of the area behind their vehicle. When the driver puts the car in reverse, the overhead camera turns on and displays a live video feed of what's behind the car on the infotainment screen. This system can be extremely helpful when trying to avoid obstacles while backing up, and it's also a great way to keep an eye on children or pets who may be in the area.
