Order of Play
Tracks will be played in the following order:
•
Play will begin from the first track in the first playlist
and will continue sequentially through all tracks in
each playlist. When the last track of the last playlist
has been played, play will continue from the first
track of the first playlist.
•
If the CD does not contain any playlists, then play
will begin from the first track under the root directory.
When all tracks from the root directory have been
played, play will continue from files according to their
numerical listing. After playing the last track from the
last folder, play will begin again at the first track of
the first folder or root directory.
When play enters a new folder, the display will not
automatically show the new folder name unless
you have chosen the folder mode as the default display.
See RCL later in this section for more information.
The new track name will appear on the display.
File System and Naming
The song name that will be displayed will be the song
name that is contained in the ID3 tag. If the song name is
not present in the ID3 tag, then the radio will display the
file name without the extension (such as .mp3) as the
track name.
3-64
Track names longer than 32 characters or 4 pages will
be shortened. The display will not show parts of
words on the last page of text and the extension of the
filename will not be displayed.
Preprogrammed Playlists
You can access preprogrammed playlists which were
created by WinAmp™, MusicMatch™, or Real
Jukebox™ software, however, you will not have editing
capability. These playlists will be treated as special
folders containing compressed audio song files.
Playing a MP3
Insert a CD partway into the slot, label side up. The
player will pull it in and the CD will begin to play after the
player has read the table of contents and the file
structure and determined where the first playable track
is located. READING DISC will appear on the display.
After the MP3 has been read, the number of folders and
tracks will appear on the display, then the radio will
go back to the default display. The CD symbol will
appear on the display. If you want to insert an MP3 with
the ignition off, first press the EJECT button or push
the RCL knob. If you insert a CD with the radio off and
the ignition on, it will start to play.
