Hi My ipod nano (2nd most recent one- the one before the camera nano) buttons only work when it is plugged into my stereo ipod dock. So basically the buttons only work when it is plugged into some sort of power. Once it is taken off the dock, the buttons don't do anything. However I can reset it using the centre and menu button. This does nothing. Any help would be much appreciated because it's very frustrating. Cheers.
