How do I auto switch my backup camera?

[DrWongBurger]

I installed the px3 (1024x600 O) with Android version 7.1.2 and hooked up my backup camera to brake lights. It works fine, but I have to go into the menu and click on the AViN icon each time to view my backup camera, and click back to the homescreen if I want to do anything else every time. Is there a way to make it so the camera comes on the screen automatically when I shift into reverse, and go back to home screen when I shift into first?

Hi,you need connect the reverse camera according to the instruction of the user manuer.

When you put the car back,the reverse wire get 12v power and make the unit switch to the reverse image.
