Hers's the full instructions for the Dension as i know it
When you load the IPOD your 1-5 buttons on the H/U will be your first five playlist's on your IPOD
Pressing 1-5 will automatically load that playlist and start playing,if you want to skip to the next track in that playlist roll the roller on the remote or press the skip/fastforward button on the h/u which will look like this >>I
To get access to the rest of your playlist's on your IPOD press button 6 briefly,that will enter the menu screen where you select playlist using the skip/fastforward button on the H/U by pressing once briefly or the roller on the remote untill playlist is highlighted,to select playlist keep your finger pressed for a while on skip/forward button on the H/U.That should now show you your playlist's on your IPOD now select the playlist using the roller or the skip/fastforward button on the H/U keep pressing it once briefly ,when you see the playlist you require keep you finger pressed on skip/fastforward button for a while that will load the playlist up and you can then skip tracks like mentioned earlier.
If you want to go back to your playlist and change to another playlist you need to press button 6 again and follow the above procedure again.
At any time holding button 6 down for a while will switch the IPOD into random play mode.
If you have know all that and it won't skip track's still i think it could be f**ked
