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 4 pages are
shortened. The display does not
show parts of words on the last
page of text and the extension of
the file name is not displayed.
Preprogrammed Playlists
CDs that have preprogrammed
playlists reated using WinAmp™,
MusicMatch™, or Real Jukebox™
software can be accessed; however,
there is no playlist‐editing capability
using the radio. These playlists are
treated as special folders containing
compressed audio song files.

CHECK DISC:If this message
displays and/or the CD ejects, it
could be for one of the following
reasons:
.It is very hot. When the
temperature returns to normal,
the CD should play.
.The road is very rough. When
the road becomes smoother,
the CD should play.
.The CD is dirty, scratched, wet,
or upside down.

contact your dealer. If the radio
displays an error message, write it
down and provide it to your dealer
when reporting the problem.
CD/DVD Player
Care of the CD and DVD Player
Do not add any label to a disc.
It could get caught in the CD or
DVD player. If a disc is recorded
on a personal computer and a
description label is needed, try
labeling the top of the recorded
disc with a marking pen.
The use of CD/DVD lens cleaners
is not advised, due to the risk of
contaminating the lens of the optics
with lubricants internal to the CD
and DVD player mechanism.

Notice:If a label is added to
a CD, or more than one CD is
inserted into the slot at a time,
or an attempt is made to play
scratched or damaged CDs, the
CD player could be damaged.
While using the CD player, use
only CDs in good condition
without any label, load one CD at
a time, and keep the CD player
and the loading slot free of
foreign materials, liquids, and
debris.
If an error displays, see “CD
Messages” later in this section.Care of CDs and DVDs
If playing a CD-R or CD-RW, the
sound quality can be reduced due to
CD-R or CD-RW quality, the method
of recording, the quality of the music
that has been recorded, and the
way the CD-R or CD-RW has been
handled. Handle them carefully.
Store CD-Rs or CD-RWs in their
original cases or other protective
cases and away from direct sunlight
and dust. The CD or DVD player
scans the bottom surface of the
disc. If the surface of a disc is
damaged, such as cracked, broken,
or scratched, the disc does not play
properly or not at all. Do not touch
the bottom side of a disc while
handling it; this could damage the
surface. Pick up discs by grasping
the outer edges or the edge of the
hole and the outer edge. If the surface of a disc is soiled,
clean it with a soft, lint‐free cloth or
dampen a clean, soft cloth in a mild,
neutral detergent solution mixed
with water. Make sure the wiping
process starts from the center to
the edge.
