Is the AirDock compatible with the iPod Touch, iPod Classic, or the third generation Nano?

Unfortunately, there is no video output available with the iPod Touch, iPod Classic, or the third generation iPod Nano because Apple now requires all video out devices to have an authorization chip in order to pass a video signal. The AirDock will still allow you to play your music, but note that there are no longer visual onscreen representations of the iPod's volume levels. You can adjust the volume via remote, but the volume bar wil not appear on screen.
