Also, there is a small brown connector on the back of the radio, anyone know what that is for and how to unplug it?

I have pulled pretty hard, but I don't want to break anything.

I know this is an older thread, but I have a 2013 PE658U1 and I grounded pin 8 and the lines would come up when I put the car in reverse.

So I was hooking up a camera last night and with the wires connected, I didn't have the backup wire connected and it hit a ground and shorted something out.

Now, when I put the car in reverse, the lines do not come up.

Does anyone know what could have blown or happened? Is there any way to reset what has happened or do I need to buy a used 2013 PE658U1 to put in the vehicle?
