Preprogrammed Playlists
Preprogrammed playlists that were created using WinAmp™, MusicMatch™, or Real Jukebox™ software can be accessed; however, they cannot be edited using the radio. These playlists are treated as special folders containing compressed audio song files.
Playlists that have an .m3u or .pls file extension and are stored on a USB device may be supported by the radio with a USB port.
