Using an MP3
MP3 CD-R or CD-RW Disc
The radio plays MP3 les that were recorded on a
CD-R or CD-RW disc. The les can be recorded
with the following xed bit rates: 32 kbps, 40 kbps,
56 kbps, 64 kbps, 80 kbps, 96 kbps, 112 kbps,
128 kbps, 160 kbps, 192 kbps, 224 kbps,
256 kbps, and 320 kbps or a variable bit rate.
Song title, artist name, and album can display
when recorded using ID3 tags version 1 and 2.
Compressed Audio
The radio also plays discs that contain both
uncompressed CD audio (.CDA les) and
MP3 les. By default the radio reads only the
uncompressed audio and ignores the MP3 les.
Pressing the CAT (category) 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 les are recorded on a
CD-R or CD-RW disc.
Avoid mixing standard audio and MP3 les on
one disc.
The CD player is able to read and play a
maximum of 50 folders, 50 playlists, and
255 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 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.
226

Make sure playlists have a .mp3 or .wpl
extension (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, and might not fully display.
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.
Change playlists by using the previous and next
folder buttons, the tuner knob, or the seek buttons.
An MP3 CD-R that was recorded using no le
folders can also be played. If a CD-R contains
more than the maximum of 50 folders, 50 playlists,
and 255 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 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-R contains only compressed les,
the les are located under the root folder. The next
and previous folder functions are not displayed
on a CD-R that was recorded without folders
or playlists. When displaying the name of the folder
the radio displays ROOT.
227

When the CD-R 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 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.
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-R 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
should begin playing.
228

If the ignition or radio is turned off with a CD-R in
the player, it stays in the player. When the
ignition or radio is turned on, the CD-R 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.
The CD player can play the smaller 3 inch (8 cm)
single CD-Rs with an adapter ring. Full-size
CD-Rs and the smaller CD-Rs 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
on page 235for more information.
If there is no apparent damage, try a known
good CD.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.
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
this section.
ZEJECT:Press the CD eject button to eject
CD-R(s). To eject the CD-R that is currently
playing, press and release this button. A beep will
sound and Ejecting Disc displays. Once the
disc is ejected, Remove Disc displays. The CD-R
can be removed. If the CD-R is not removed,
after several seconds, the CD-R automatically pulls
back into the player and begins playing. For the
Six-Disc CD player, press and hold the eject button
for two seconds to eject all discs.

h(Music Navigator):Use the music navigator
feature to play MP3 les on the CD-R in order
by artist or album. Press the pushbutton located
below the music navigator label. The player scans
the disc to sort the les by artist and album ID3
tag information. It can take several minutes to scan
the disc depending on the number of MP3 les
recorded to the CD-R. The radio can begin playing
while it is scanning the disc in the background.
When the scan is nished, the CD-R begins
playing again.
Once the disc has been scanned, the player
defaults to playing MP3 les 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-R and begins
playing MP3 les by that artist. If you want to listen
to MP3 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 displays.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. The album name
displays on the second line between the arrows and
songs from the current album and 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 and begins playing MP3 les
from that album.
To exit music navigator mode, press the pushbutton
below the Back label to return to normal MP3
playback.
BAND:Press this button to listen to the radio
while a CD is playing. The CD remains inside the
radio for future listening.

a CD while listening to the radio. The CD icon and a
message showing disc and/or track number
displays while a CD is in the player. Press this
button again and the system automatically

portable audio player. If a portable audio player is
not connected, “No Aux Input Device” displays.
