Keep a close eye on what’s behind you with this easy-to-install back up camera system. Replacement rearview mirror features a 3.5" LCD screen to give you a clear, unobstructed view of everything behind you in one convenient place. No more looking from screen to mirror as you back up your vehicle. The water-resistant color camera easily attaches to your rear license-plate bracket and sends the crisp, clear, full-color picture to the screen via a wireless transmitter. A great safety addition to any vehicle, from cars to RVs or even boat trailers and tow-behind campers. Display plugs into your vehicle’s 12-volt outlet, while the camera and transmitter are wired directly into the taillight harness. Display mirror dimensions: 3"H x 10.6"W x 13.8"D.
