Hi guys, so i have the same problem as this and i have read every post available including the link above!!. the problem is that i just want to test my head unit before buying a camera kit, so i what i did was put +12v to pin 5 on the 20 pin connector and assumed it should activate the screen to "reverse camera" mode and just not display anything other than the warning to "check surroundings" as there is no camera connected. But instead it didnt do anything, can someone please help me! do i need to actually connect the camera (-) and (+) video feed to pins 11 and 12 as well? i would have thought that all the head unit needed to switch to rear camera mode would be the +12v trigger wire
