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
will 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 appears
on the display. The CD should begin playing
and the CD symbol appears on the display.
If the ignition or radio is turned off with a CD in the
player it stays in the player. When the ignition or
radio is turned on, the CD starts to play where it
stopped, if it was the last selected audio source.
As each new track starts to play, the track number
appears on the display.
The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs
and the smaller CDs are loaded in the same
manner.
If playing a CD-R, the sound quality (and playback
performance) may be reduced due to the CD-R
quality, method of recording, the quality of the
music that has been recorded, and the way the
CD-R has been handled. For better playback
performance when home burning audio discs, use
brand named CD media showing the Compact
Disc™, and a burn rate no faster than 12X.
