So, I only listen to pre-recorded music on my bike, as I have taken the antenna off completely. I use a USB thumb drive with about 400 songs on it. Has worked fine until about 2 weeks ago. Suddenly, for no reason (that I am aware of) the left hand control that would advance the track stopped working. The "joystick" works when changing volume, but not when pushing right and left to change track. Worked fine for months and I know of no settings that I changed. The control works for regular radio, etc, just not USB drive. So, I ask my dealer service guys..they have no clue. They messed around with it but could not figure it out..so, I figured- not a big deal. Well, when I left the dealer my stereo started repeating the same song all the way home. I figured one of the guys just turned on the repeat feature and I'd fix it when I got home. I turned off "repeat" and set it to "shuffle". NO DICE!!! It is still repeating 1 song over and over infinitely!!! WHen you look at playlists, etc it only shows there being 1 song to play...but, if you do a "Find" it sees the other songs..so they are there, just wont play them. Anyone have a clue how I can fix this?? Or reset the whole system or something?? I like the Allman Brothers, but don't want to listen to Whipping Post for the rest of my life on repeat.
