Order of Play
Tracks recorded to the CD-R or CD-RW are played in
the following order:
•
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.
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 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.
