We sold & installed a Compustar CS7102AS in a GMC Envoy 2000. The system provides 2 – Two Way LCD Remotes that provides 1500 ft. range. The LCD remote; this provides 2 way communication on the screen. No need to think what is the status on your vehicle. You can just look on the LCD screen. System installation includes flashing lights, impact sensor, protection on door, hood, trunk, aftermarket siren & starter kill.
