Hey everyone! So I have the oem touch screen radio that I had to unplug to check something behind my dash the other day and ever since then the radio stopped working completely. When I turn my car on nothing happens on screen, I pressed all of the buttons and nothing, the only time the radio turns on is when I throw it in reverse I still receive video feed from my back up camera which tells me that the unit is still receiving power and that the screen is not broken, also my usb port stopped working as well which after reading through some forums here is because it is connected to my radio. I bought a Multimeter checked all of the ribbon cables inside the unit everything works, the 20a fuse for the radio in the engine bay works I checked that as well so I am at a loss as to where to go next. Nothing is broken or damaged I believe that maybe a cable somewhere may be disconnected? Do any of you know what would cause the radio to only display backup camera feed and nothing else?
