I Need Help with Stereo wiring problem!

i have a Pioneer AVH-4200dvd double din stereo head unit which i installed myself a couple of years ago. a short time after the install i noticed the radio will change stations by itself. a couple of years down the road it has gotten to be an annoying problem (and slightly more common) is it possible it is a wiring problem? or is it a glitch in my head unit? im thinking of taking it apart and re crimping the wires to see if that fixes it. should i even bother? HELP PLEASE!

 

I posted in your other thread but its likely a glitch in your system. Another thought though is to make sure someone didn't have a brain fart and plugged something into the remote input plug. Its the little 3.5mm jack on the back side of your radio.
