CHECK CD:If this message appears on the
display 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.
You are driving on a very rough road.
When the road becomes smoother, the CD
should play.
The CD is dirty, scratched, wet, or
upside down.
The air is very humid. If so, wait about an
hour and try again.
There could have been a problem while
burning the CD.
The label could be caught in the CD player.
If the CD is not playing correctly, for any
other reason, try a known good CD.
If any error occurs repeatedly or if an error cannot
be corrected, contact your dealer. If the radio
displays an error message, write it down and
provide it to your dealer when reporting the
problem.
270

Listening to a DVD
If your vehicle has the Rear Seat
Entertainment (RSE) system and a DVD
is playing, the DVD symbol displays indicating
that the DVD is available and can be listened to
through your vehicle’s speakers.
To listen to the DVD, press the CD AUX button
until RSE displays. The current radio source stops
and the DVD sound comes through the speakers.
To stop listening to the DVD, press the CD
AUX button, if a CD is loaded, or press the BAND
button to select a different source.
When the RSE system is turned off, the DVD
symbol goes off of the radio display and RSE OFF
displays. The radio returns to the last radio
source that you were listening to.
SeeRear Seat Entertainment System on page 280
for more information.
Using an MP3
MP3 CD-R Disc
MP3 Format
If you burn your own MP3 disc on a personal
computer:
Make sure the MP3 les are recorded on a
CD-R disc.
Do not mix standard audio and MP3 les on
one disc.
Make sure playlists have a .m3u or .wpl
extension, other le extensions may not work.
Files can be recorded with a variety of xed or
variable bit rates. Song title, artist name, and
album is available for display by the radio
when recorded using ID3 tags version 1 and 2.
Create a folder structure that makes it easy
to nd songs while driving. Organize songs
by albums using one folder for each album.
Each folder or album should contain 18 songs
or less.
Make sure to nalize the disc when burning
an MP3 disc, using multiple sessions. It is
usually better to burn the disc all at once.
271

The player is able to read and play a maximum
of 50 folders, 50 playlists, 10 sessions, and
255 les. Long le names, folder names, or playlist
names can use more disc memory space than
necessary. To conserve space on the disc,
minimize the length of the le, folder, or playlist
names. You can also play an MP3 CD that
was recorded using no le folders. The system
can support up to 11 folders in depth, though, keep
the depth of the folders to a minimum in order
to keep down the complexity and confusion
in trying to locate a particular folder during
playback. If a CD contains more than the
maximum of 50 folders, 50 playlists, 10 sessions,
and 255 les the player lets you access and
navigate up to the maximum, but all items over
the maximum are ignored.
Root Directory
The root directory is treated as a folder. If the root
directory has compressed audio les, the directory
displays as F1 ROOT. All les contained directly
under the root directory are accessed prior to any
root directory folders. However, playlists (Px) are
always accessed before root folders or les.
Empty Directory or Folder
If a root directory or a folder exists somewhere in
the le structure that contains only
folders/subfolders and no compressed les directly
beneath them, the player advances to the next
folder in the le structure that contains compressed
audio les. The empty folder does not display.
No Folder
When the CD contains only compressed les, the
les are located under the root folder. The next
and previous folder functions do not function on a
CD that was recorded without folders or playlists.
When displaying the name of the folder the
radio displays ROOT.
When the CD contains only playlists and
compressed audio les, but no folders, all les are
located under the root folder. The folder down
and the folder up buttons search playlists (Px) rst
and then goes to the root folder. When the
radio displays the name of the folder the radio
displays ROOT.
272

Order of Play
Tracks are played in the following order:
Play begins from the rst track in the rst
playlist and continues sequentially through
all tracks in each playlist. When the last track
of the last playlist has played, play continues
from the rst track of the rst playlist.
If the CD does not contain any playlists, then
play begins from the rst track under the root
directory. When all tracks from the root
directory have played, play continues from
les according to their numerical listing. After
playing the last track from the last folder,
play begins again at the rst track of the rst
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
le 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 lename
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 les.
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, rst
press the eject button or the DISPL knob.
273

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 displays.
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 can be
reduced due to CD-R quality, the method of
recording, the quality of the music that has been
recorded, and the way the CD-R has been
handled. There can be an increase in skipping,
difficulty in nding tracks, and/or difficulty in loading
and ejecting. If these problems occur, check the
bottom surface of the CD. If the surface of the CD
is damaged, such as cracked, broken, or
scratched, the CD will not play properly. If the
surface of the CD is soiled, seeCare of Your CDs
and DVDs on page 299for more information.
If there is no apparent damage, try a known
good CD.Do not add any label to a CD, it could get caught
in the CD player. If a CD is recorded on a
personal computer and a description label is
needed, try labeling the top of the recorded CD
with a marking pen.
Notice:If you add any label to a CD, insert
more than one CD into the slot at a time, or
attempt to play scratched or damaged CDs, you
could damage the CD player. When 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.
