Playing an MP3 CD-R or CD-RW Disc
The radio may have MP3 CD-R or CD-RW disc
capability. For more information, seeUsing an MP3on
page 4‑87later in this section.
CD Messages
CHECK DISC: If an error message displays 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.
.The road is very rough. 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 there is no apparent damage, 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 while reporting the problem.
Using the Auxiliary Input Jack
The radio system has an auxiliary input jack located on
the lower right side of the faceplate. This is not an audio
output; do not plug the headphone set into the front
auxiliary input jack. However, an external audio device
such as an iPod, laptop computer, MP3 player, CD
changer, or cassette tape player, etc. can be connected
to the auxiliary input jack for use as another source for
audio listening.
Drivers are encouraged to set up any auxiliary device
while the vehicle is in P (Park). See Defensive Driving
on page 5‑2for more information on driver distraction.
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio's front auxiliary input jack.
While a device is connected, press the radio CD/AUX
button to begin playing audio from the device over the
vehicle speakers.
O(Power/Volume): Turn to increase or decrease
the volume of the portable player. Additional volume
adjustments might need to be made from the portable
device.

BAND:Press to listen to the radio while a portable
audio device is playing. The portable audio device
continues playing until it is stopped or turned off.
CD/AUX (CD/Auxiliary): Press to play a CD while a

system begins playing audio from the connected
portable audio player. If a portable audio player is not

Using an MP3
MP3 CD-R or CD-RW Disc
The radio may have MP3 capability. With this feature,
the radio plays MP3 files that were recorded on a CD-R
or CD-RW disc. Song title, artist name, and album can
display when files are recorded using ID3 tags version
1 and 2.
Compressed Audio
The radio also plays discs that contain both
uncompressed CD audio (.CDA files) and MP3 files.
By default the radio reads only the uncompressed audio
and ignore the MP3 files. Pressing the CAT button
toggles between compressed and uncompressed audio
format.
MP3 Format
If you burn your own MP3 disc on a personal computer:
.Make sure the MP3 files are recorded on a CD-R
or CD-RW disc.
.Do not mix standard audio and MP3 files on
one disc.
.The CD player is able to read and play a maximum
of 50 folders, 50 playlists, and 255 files.
.Create a folder structure that makes it easy to find
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
8 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 or .wpl extension
(other file extensions might not work).
4-87

.Minimize the length of the file, folder or playlist
names. Long file, folder, or playlist names, or a
combination of a large number of files and folders,
or playlists can cause the player to be unable to
play up to the maximum number of files, folders,
playlists, or sessions. If you wish to play a large
number of files, folders, playlists, or sessions,
minimize the length of the file, folder, or playlist
name. Long names also take up more space on
the display, potentially getting cut off.
.Finalize the audio disc before burning it. Trying to
add music to an existing disc can cause the disc
not to function in the player.
Playlists can be changed by using the previous and
next folder buttons, the
fknob, or the seek buttons.
An MP3 CD-R or CD-RW that was recorded using no
file folders can also be played. If a CD contains more
than the maximum of 50 folders, 50 playlists, and
255 files, the player lets you access and navigate up
to the maximum, but all items over the maximum cannot
be accessed.
Root Directory
The root directory of the CD is treated as a folder. If the
root directory has compressed audio files, the directory
displays as F1 ROOT. All files contained directly under
the root directory are accessed prior to any root
directory folders. However, playlists (Px) are always
accessed before root folders or files.
Empty Directory or Folder
If a root directory or a folder exists somewhere in the
file structure that contains only folders/subfolders and
no compressed files directly beneath them, the player
advances to the next folder in the file structure that
contains compressed audio files. The empty folder does
not display.
No Folder
When the CD contains only compressed files, the files
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 files, but no folders, all files are located under the
root folder. The folder down and the folder up buttons
searches playlists (Px) first and then goes to the root
folder. When the radio displays the name of the folder
the radio displays ROOT.
4-88

Order of Play
Tracks recorded to the CD-R or CD-RW are played in
the following order:
.Play begins from the first track in the first playlist
and continues sequentially through all tracks in
each playlist. When the last track of the last playlist
has played, play continues from the first track of
the first playlist.
.Play begins from the first track in the first folder
and continues sequentially through all tracks in
each folder. When the last track of the last folder
has played, play continues from the first track of
the first folder.
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.
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 file
name without the extension (such as .mp3) as the
track name.
Track names longer than 32 characters or four pages
are shortened. The display does not show parts of
words on the last page of text and the extension of the
filename is not displayed.
Preprogrammed Playlists
Preprogrammed playlists that were created using
WinAmp™, MusicMatch™, or Real Jukebox™ software
can be accessed, however, you do not have playlist
editing capability using the radio. These playlists are
treated as special folders containing compressed audio
song files.
4-89

h(Music Navigator):If the radio has the MP3
feature, it has the music navigator feature to play MP3
files on the CD-R or CD-RW in order by artist or album.
Press the pushbutton located below the music navigator
tab. The player scans the disc to sort the files by artist
and album ID3 tag information. It can take several
minutes to scan the disc depending on the number of
MP3 files recorded to the CD-R or CD-RW. The radio
might begin playing while it is scanning the disc in the
background. When the scan is finished, the CD begins
playing again.
Once the disc has scanned, the player defaults to
playing MP3 files in order by artist. The current artist
playing is shown on the second line of the display
between the arrows. Once all songs by that artist
are played, the player moves to the next artist in
alphabetical order on the CD and begins playing MP3 files by that artist. If you want to listen to MP3 files 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 displays.
To change from playback by artist to playback by
album, press the pushbutton located below the Sort By
tab. From the sort screen, push one of the buttons
below the album button. Press the pushbutton below
the back tab 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
have played, the player moves to the next album in
alphabetical order on the CD and begins playing MP3
files from that album.
To exit music navigator mode, press the pushbutton
below the Back tab to return to normal MP3 playback.
