Most Popular Smartphone Display for 2018 GMC Sierra 1500

These work and are very easy to deploy

Didn't work as promised, led light always came on annoying people following, Suburban towing 24' trailer didn't work. Tried contacting Hoppkins no reply. I would not recommend, as a rear view camera ok just remember to turn off led lights as if your actually using it you will as when there on it is almost unusable.
