If your nano is of the 1.5" variety you will have to remove the 'click wheel' first. This is achieved by lifting each side (top, bottom, left and right) of the wheel, carefully saparating it from the pads it's glued to. This glue will stay sticky so you can stick it back down when you're finished. Be careful not to break these pads or your 'wheel' will not re-attach.
Good luck
