Clean the camera installation surface. Mount the camera on the license plate. Fix the camera temporarily with the existing screws. Complete all of the required connections, including the connection between the camera and monitor. Change the shift lever to the R (Reverse) range to view the image of the rear of the vehicle. Unbolt the screws on top of the camera to adjust the camera angle so that the rear part of the vehicle or the rear bumper is visible at the bottom of the monitor screen. After adjusting the camera angle, tighten the screws firmly. Fix the camera firmly in position. (We recommend you to ask a professional for help if you have no experience on installing a car rear view system)
