Hi Greg, I saw that you posted a question which I also shared. Has anyone ever gotten back to you with an answer? I too would like to set up my car with a total of 4 cameras and have them switch and automatically turn on and off with the turn signals. I'm curious to find out where you ended up with this. Your help is greatly appreciated. Thanks Brian
Yes, I did set up my car with 2 extra cameras, which I can switch on through the aux input of the head unit. To do it properly, you should buy the speed sensor over-ride, so that the cameras can be switched on at any time when the car is moving. There is a wiring diagram which explains how to wire it into the backup camera circuit, but I never pursued it that far.
