Instrument Panel File System and Naming The song name that is displayed is the song name that is contained in the ID3 tag. If the song name is not present in the ID3 tag, then the radio displays the file name without the extension (such as .mp3) as the track name. Track names longer than 32 characters or four pages are shortened. Parts of words on the last page of text and the extension of the filename displays. 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. Playing an MP3/WMA (In Either the DVD or CD Slot) Insert a CD-R or CD-RW disc partway into either the top or bottom slot, label side up. The player pulls it in, and the CD-R or CD-RW should begin playing. Depending on the format of the disc, a softkey menu appears and allows navigation of the disc. The menu reads left to right as RDM (Randomize song play order), a Folder icon with left and right arrows (to move up or down through available folders), a PL tag if the disc has a Playlist available, and a Music Navigator tag. If a Playlist tag is shown, toggling this key brings up a Folder softkey only or the menu as previously described. If the ignition or radio is turned off with a CD-R or CD-RW disc in the player it stays in the player. When the ignition or radio is turned back 3-101 on, the CD-R or CD-RW starts to play where it stopped, if it was the last selected audio source. As each new track starts to play, the track number and song title displays. Z CD (Eject): Press and release this button to eject the CD-R or CD-RW that is currently playing in the bottom slot. A beep sounds and Ejecting Disc displays. Once the disc is ejected, Remove Disc displays. The CD-R or CD-RW disc can be removed. If the CD-R or CD-RW disc is not removed, after several seconds, the CD-R or CD-RW disc automatically pulls back into the player. If loading and reading of a CD cannot be completed, such as unknown format, etc., and the disc fails to eject, press and hold this button for more than five seconds to force the disc to eject.
