I have a backup camera in my 14 GMC Sierra. The lady has a backup camera AND the backup radar in her 13 GMC Terrain Denali. Personally, I find that between the two, the radar if more beneficial. There are circumstances of bright sun where the camera is bleached out - either through the lense or through the window onto the screen itself - and instances of rain where the camera is subject to water droplets on the lense making it tough to discern what's behind. The radar is unaffected by these conditions. Though it might not show you an image, it tells you that theres a reason to stop with more dependability than the camera, in my opinion. Wish my truck had the backup radar as well or even instead of the camera
