CD Messages
CHECK CD:If this message displays and/or the CD
ejects, 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 could have been a problem while burning
the CD.
The label could 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/retailer. If the radio
displays an error message, write it down and provide
it to your dealer/retailer when reporting the problem.

Using an MP3
MP3/WMA Disc
MP3/WMA Format
If you burn your own MP3 disc on a personal computer:
Make sure the MP3 les are recorded on a
CD-R disc.
Standard audio, MP3 les, and WMA les can be
mixed on one CD.
Make sure playlists have a .mp3 or .wpl extension,
other le extensions might not work.
Files can be recorded with a variety of xed or
variable bit rates. Song title, artist name, and album
is 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.
The player is able to read and play a maximum of
253 folders, 50 playlists, 20 sessions, and 949 les.
Long le names, folder names, or playlist names mayuse more disc memory space than necessary.
To conserve space on the disc, minimize the length
of the le, folder, or playlist names. An MP3 CD that
was recorded using no le folders can also be played.
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 253 folders,
50 playlists, 20 sessions, and 949 les, the player
lets you access and navigate up to the maximum,
but all items over the maximum are played.
Root Directory
The root directory 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.
3-82

No Folder
When the CD contains only compressed les, the les
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 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 are played in the following order:
If CD audio tracks are available they will be played
rst, otherwise 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 DISPL
(display) later in this section for more information.
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 le name 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.
