Order of Play
Tracks 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.
•
If the CD does not contain any playlists, then
play begins from the first track under the root
directory. When all tracks from the root
directory have played, play continues from
files according to their numerical listing. After
playing the last track from the last folder,
play begins again at the first track of the first
folder or root directory.
When play enters a new folder, the display does
not automatically show the new folder name unless
the folder mode has been chosen as the default
display. See DISPL later in this section for
more information. The new track name appears
on the display.
File System and Naming
The song name that displays 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
does not display.
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
Insert a CD partway into the slot, label side up. The
player pulls it in, and READING displays. The CD
should begin playing and the CD symbol displays.
If you want to insert a CD with the ignition off, first
press the eject button or the DISPL knob.
