So I bought 1 off amazon from CHINA about 5 yrs ago. It was like $30. It was working intermittently a few weeks back but now it has quit. I wiggled the gear box and got nothing. I did change a fuse that blew on the license plate bulb. I tried changing to different input but don't remember the original spot. The radio is a pioneer AVH2700BS. ANY HELP!! tried youtube video but no help.
