DVD Player)
MP3/WMA CD-R or CD-RW Disc
Compressed Audio or Mixed Mode Discs
The radio also plays discs that contain both
uncompressed CD audio (.CDA les) and
MP3/WMA les depending on which slot the disc
is loaded into. By default the radio reads only
the uncompressed audio (.CDA) and ignores the
MP3/WMA les on the DVD deck. On the CD
deck, pressing the CAT button toggles between
compressed and uncompressed audio format, the
default being the uncompressed format (.CDA).

MP3/WMA Format
If you burn your own MP3/WMA disc on a
personal computer:
Make sure the MP3/WMA les are recorded
on a CD-R or CD-RW disc.
Do not mix standard audio and MP3/WMA
les on one disc.
The CD player (lower slot) is able to read and
play a maximum combination of 512 les and
folders. The DVD player (upper slot) is able to
read 255 folders, 15 playlists and 40 sessions.
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.
Avoid subfolders. The system can support up to
eight subfolders deep, however, keep the total
number of folders to a minimum in order to
reduce the complexity and confusion in trying to
locate a particular folder during playback.
Make sure playlists have a .m3u, .wpl
or .pls extension as other le extensions may
not work.
Minimize the length of the le, folder or playlist
names. Long le, folder, or playlist names, or a
combination of a large number of les and
folders, or playlists can cause the player to be
unable to play up to the maximum number of
les, folders, playlists, or sessions. If you wish
to play a large number of les, folders, playlists,
or sessions, minimize the length of the le,
folder, or playlist name. Long names also take
up more space on the display, potentially
getting cut off.
Finalize the audio disc before you burn it.
Trying to add music to an existing disc can
cause the disc not to function in the player.
Root Directory
The root directory of the CD-R or CD-RW 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.
346

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-R or CD-RW contains only
compressed les, the les are located under the
root folder. The next and previous folder function
does not function on a CD-R or CD-RW that was
recorded without folders or playlists. When
displaying the name of the folder the radio
displays ROOT.
When the CD-R or CD-RW 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.
Order of Play
Tracks recorded to the CD-R or CD-RW 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.
Play begins from the rst track in the rst
folder and continues sequentially through
all tracks in each folder. When the last track of
the last folder has played, play continues
from the rst track of the rst folder.
When play enters a new folder, the display does
not automatically show the new folder name unless
the folder mode was chosen as the default
display. The new track name displays.
347

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, 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
displays.
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/WMA (In Either the DVD or
CD Slot)
Insert a CD-R or CD-RW partway into either the top
or bottom slot, label side up. The player pulls it in,
and the CD-R or CD-RW should begin playing.
Depending on the format of the disc, a softkey
menu appears and allows navigation of the disc.
The menu reads left to right as RDM (Randomize
song play order), a Folder icon with left and
right arrows (to move up or down through available
folders), a PL tag if the disc has a Playlist
available, and a Music Navigator tag. If a Playlist
tag is shown, toggling this key brings up a
Folder softkey only or the menu as previously
described.
If the ignition or radio is turned off with a CD-R or
CD-RW in the player, it stays in the player.
When the ignition or radio is turned on, the CD-R
or CD-RW starts to play where it stopped, if it
was the last selected audio source.
As each new track starts to play, the track number
and song title displays.
348

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. 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
does not play properly. If the surface of the CD is
soiled, seeCare of Your CDs and DVDs on
page 370for more information.
If there is no apparent damage, try a known
good CD.
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.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.
If an error displays, see “CD Messages” later in
