When reverse is first engaged, a driver may not look at the video screen immediately before moving. However, a proximity sensor will provide an audible alert if there is an obstacle detected and immediately attract the driver`s attention to the screen. How to test a combined system There are currently no standards or regulations governing such devices and so if you decide to go ahead and modify your vehicle by fitting a combined system to it, you should seek a pre-purchase demonstration to understand its strengths and weaknesses. This easy 10 step test will help you do this: 1. Turn the ignition to ‘on`, but do not start the car. Engage reverse. 2. Make sure the video screen qui
