Make backing your vehicle safer with a backup sensor system. The BackZone by Rostra features four flush mount sensors that mount in the rear bumper and detect objects behind the vehicle and alerts you to them as you back up. A small display mounts on the headliner above the rear view mirror and gives you an audible and visual alert when objects behind you are detected. A LED indicator shows you on which side the object is located and a digital readout tells you how many feet behind you the object is. In addition, the unit beeps to alert you when an object is detected and beeps faster as you get closer to the object. Sensors can be painted to match the vehicle for an additional charge. Three year warranty. Works on most vehicles. Price includes professional installation.
