Push the tab into the plug. I had to use a vise grip to get it out. It is in there pretty tight.
Yesterday I went to pick up the RV to take it to get the radio fixed. When I turned the coach batteries, the radio and the cameras came on. I disconnected everything several times and it still works perfectly.
I've read where to disconnect it from power for 24 hours, tried that before and it didn't work.
Just hope it keeps working.
