Playing a CD
Insert a CD partway into the slot, label side up. The
player pulls it in and the CD should begin playing.
If you want to insert a CD with the ignition off, rst
press the eject button or the DISP knob.
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.
When the CD is inserted, the CD symbol appears
on the display. 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 may 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 may 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 on page 231
for 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 appears on the display, see
“CD Messages” later in this section.

CD Messages
CHECK CD:If this message appears on the
display and/or the CD comes out, 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 may have been a problem while
burning the CD.
The label may 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.
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 .mp3 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 are 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.
222

The player will be 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 may 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 is displayed 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 does 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 go to the root folder. When the
radio displays the name of the folder the radio
displays ROOT.
223

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 DISP (display) later in this section for
more information. The new track name appears
on the display.
File System and Naming
The song name that is displayed is the song name
that is contained in the ID3 tag. If the song name
is not present in the ID3 tag, the radio displays the
le name without the extension (such as .mp3) as
the track name.
Track names longer than 32 characters or 4 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
appears on the display. If you want to insert a
CD with the ignition off, rst press the eject button
or the DISP knob.
