The iPod Panel Dock fits all first, second, and third generation iPod
devices. It does not fit the iPod Mini, or any of the iPod knockoffs that
are out there. The iPod Dock can be installed to allow access to either
the top plugs or the bottom plug. Just flip it the way you want it to go
and mount it in your panel. The top plugs are useful for simple headphone-only
connections, while the bottom plug allows you to fully integrate your iPod
into your intercom and power system (a separate cable is required.)
