I installed a px6 10.4 inch vertical screen unit in my 2003 Lexus GX470. The install was amazingly easy. I added an Etsy license plate backup camera, also pretty easy install however when I put the car in reverse, the image from the camera doesn’t come up. If I go to Apps, hit the system app Car Monitor, then the camera works as anticipated, no display when in park but pops up when I put the car in reverse.
when I originally installed the unit, I only got sound from the right front speakers and would never have found the amp controls in “Console” if it weren’t for a YouTube video. Is there another setting to allow the backup camera to override all other apps when the car goes into reverse?
