Why won't RDS work with my 4th Generation iPod, iPod mini, or iPod photo?

The iPod mini and the 4th Generation iPod (including the iPod Photo) do not support communication of track information to the iTrip AutoPilot, so you will not see RDS data displayed on your radio when using one of these iPods.

Other than that, charging, transmission, and transport control functions are fully supported with these iPods.
