Here’s the problem. I was playing my MP3 player through the Aux port and have lost all radio controls. The volume won’t work or even give me a display of the current setting, Can’t cut the Aux function off, the FM on, the Intercom on, or CB on. Nothing works! No mode control on either side. No control from handlebars or from control pad on tank. NOTHING!! Only thing that shows up is the Mute light. This has happened twice. First time it reset after cutting the switch off and back on. Not happing this time. Removed the MP3 player and tried all controls again, with same nothing results. Will try removing the battery cable tomorrow and see if that works. Anyone else have any other viable suggestions?
