When I put my non-NAV CD changer into "disc random" mode, when it reaches the end of a song, it will automatically choose an MP3 at random from any folder on the disc. However, if a song comes on that I want to skip, I cannot seem to tell it to go to the "next" random track. I can only seem to go track up/down from whatever is currently playing. Anybody know a way to tell the unit to choose a new random song without waiting for the current one to finish playing?
