I've been experiencing a similar bug that may be related to your slow motion. I just got a new car and I haven't installed the player yet so I've just left it plugged into AC power on my desk for days. Everthing seemed normal until after I upgraded to 10. Now after the unit has been asleep for a couple hours with the white LED flashing I can't get the unit to wake up by pressing the controller. And if it does wake up the music is jittery and the visuals don't work correctly. A couple times I've been pressing the remote buttons, and the unit will beep but nothing happens on the display. I'm not sure what to make of this but a reboot fixes it right away.
