Designed for those customers that want an audible alert with an entry level LCD Display

When reversing, the 4 rear sensors that are installed on back bumper send ultrasonic waves to detect obstacles behind the vehicle. Then controller receives signal & transmits to the LCD display. The LCD is a mini version compared to other backup sensor system on the market. It is so convenient you can mount right on top of your rearview mirror to keep the interior neat without any messy installations.
