Decided to mount the iPhone on the Iron Aces mount today and listen to some Carpenters - just kidding - I think it was Captain and Tenile. I've got a very strange thing going on, and wondered if anyone else has experienced it. Whenever I shift gears, the song changes. Upshift, downshift, I get treated to a new song. It's as if I'm hitting the right hand button, the one that advances the audio selection. If I'm at a steady speed or stopped the selected tune plays as expected. It also advances when I hit a significant bump. Scratching my head over this one. Any ideas?
