I'm running 2.0. When I turn the small knob, it adjusts the volume. When I turn the larger knob, it seeks fwd/reverse through the track. The middle button in the back doesnt do anything and the two buttons in the rear act like up and down arrows. The two side buttons do shuffle and something else I forget. I can't tell that shift does much of anything except shuffle through the visuals.

Maybe Im missing something?
