Hi, i want to install something and from my understanding in order to switch the view to video input in the back of the unit i need to do something with that reverse detection wire (from my understanding that is the only way), what does it connect to: reverse lights? any other 12v? or just ground? couldn't find anything in manual unless I'm just blind, I'm pretty sure Ive seen a how to install a rear camera but i cant find it any more for some reason.
any help would be greatly appreciated.
