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 is able to read and play a
maximum of 50 folders, 15 playlists, and
a combined total of 512 folders and les.
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 .mp3 or .wpl
extension (other le extensions might
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
might cause the disc not to function in
the player.
Playlists can be changed by using the previous
and next folder buttons, the tuner knob, or
the seek buttons. An MP3/WMA CD-R or CD-RW
that was recorded can also be played using no
le folders. If a CD-R or CD-RW contains
more than the maximum of 50 folders, 15 playlists,
and a combined total of 512 folders and les,
the player lets you access and navigate up to the
maximum, but all items over the maximum are
not accessible.

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 the CD label. 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.
If a disc contains both uncompressed CD
audio (.CDA) and MP3/WMA les, a folder under
the root directory called CD accesses all of
the CD audio tracks on the disc.
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 display on a CD-R or CD-RW that
was recorded without folders or playlists.
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.
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.
297

When play enters a new folder, the display does
not automatically show the new folder name unless
you have chosen the folder mode as the default
display. The new track name displays.
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/WMA
Insert a CD-R or CD-RW partway into the slot
(Single CD Player), or press the load button and
wait for the message to insert disc (Six-Disc
CD Player), label side up. The player pulls it in,
and the CD-R or CD-RW should begin playing.
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.
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.

Once all songs by that artist are played, the
player moves to the next artist in alphabetical
order on the CD-R or CD-RW and begins playing
MP3/WMA les by that artist. To listen to
MP3/WMA les by another artist, press the
pushbutton located below either arrow button.
The CD goes to the next or previous artist
in alphabetical order. Continue pressing either
button until the desired artist is displayed.
To change from playback by artist to playback
by album, press the pushbutton located below
the Sort By label. From the sort screen, push
one of the buttons below the album button.
Press the pushbutton below the back label to
return to the main music navigator screen.
Now the album name displays on the second line
between the arrows and songs from the current
album begins to play. Once all songs from
that album are played, the player moves to the
next album in alphabetical order on the CD-R
or CD-RW and begins playing MP3/WMA les
from that album.
To exit music navigator mode, press the
pushbutton below the Back label to return
to normal MP3/WMA playback.BAND:Press this button to listen to the radio
when a CD is playing. The CD remains inside the
radio for future listening.
CD/AUX (CD/Auxiliary):Press this button to play
a CD when listening to the radio. The CD icon
and a message showing disc and/or track number
displays when a CD is in the player. Press this
button again and the system automatically
searches for an auxiliary input device such as a
portable audio player. If a portable audio player is
not connected, “No Input Device Found” displays.
Using an MP3 (Radio with CD
and 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.

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.
302

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

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:

Navigation/Radio System
Your vehicle may have a navigation radio system.
The navigation system has built-in features
intended to minimize driver distraction. Technology
alone, no matter how advanced, can never
replace your own judgment. See the Navigation
System manual for some tips to help you
reduce distractions while driving.
Rear Seat Entertainment System
Your vehicle may have a DVD Rear Seat
Entertainment (RSE) system. The RSE system
works with the vehicle’s audio system. The
DVD player is part of the front radio. The RSE
system includes a radio with a DVD player, a video
display screen, audio/video jacks, two wireless
headphones, and a remote control. SeeRadio with
CD and DVD on page 278for more information
on the vehicle’s audio/DVD system.
Before You Drive
The RSE is designed for rear seat passengers
only. The driver cannot safely view the video
screen while driving and should not try to do so.
In severe or extreme weather conditions the
RSE system might not work until the temperature
is within the operating range. The operating
range for the RSE system is above−4°F (−20°C)
or below 140°F (60°C). If the temperature of
your vehicle is outside of this range, heat or cool
the vehicle until the temperature is within the
operating range of the RSE system.
