On my 2011 Road Glide Ultra I discovered an issue with my radio and speaker "rocker" switch. The rocker switch use to work fine. From its off position, moving the switch to on use to bring on only the front speakers and moving to the fully on position it would bring on the Tour Pack speakers. Now when I turn the switch from the off position to the front speaker position only the rear speakers would work. Question, I suspect the speaker switch needs to be replaced. Has anyone experienced the same issue? Does anyone have a recommendation?
