Order of Play Tracks recorded to the CD-R or CD-RW are played in the following order: 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. • Play begins from the first track in the first playlist and continues sequentially through all tracks in each playlist. When the last track of the last playlist has played, play continues from the first track of the first playlist. • Play begins from the first track in the first folder and continues sequentially through all tracks in each folder. When the last track of the last folder has played, play continues from the first track of the first folder. When play enters a new folder, the display does not automatically show the new folder name unless you have chosen the folder mode as the default display. The new track name displays. Playing an MP3/WMA (In Either the DVD or CD Slot) Insert a CD-R or CD-RW 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 you turn off the ignition or radio with a CD-R or CD-RW in the player it stays in the player. When you turn on the ignition or radio, the CD-R 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. 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. 3-104
