If the ignition or radio is turned off with a CD in the player, it will stay in the player. When a CD is in the player and the ignition is turned on, the radio must be turned on before the current CD will start playback. When the ignition and radio are turned on, the CD will start playing where it stopped, if it was the last selected audio source.

The CD player can play the smaller 3 inch (8 cm) single CDs with an adapter ring. Full-size CDs and the smaller CDs are loaded in the same manner.

If playing a CD-R, the sound quality may 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 may be an increase in skipping, difficulty in finding 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, see Care of Your CDs for more information.

If there is no apparent damage, try a known good CD.

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 instead.

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.

If an error appears on the display, see "CD Messages" later in this section.

Using an MP3 CD

MP3 Format

If you burn your own MP3/WMA disc on a personal computer:

    • Make sure the MP3/WMA files are recorded on a CD-R disc.
    • Do not mix standard audio and MP3/WMA files on one disc.
    • Make sure each MP3/WMA file has a .m3u or .wma extension, other file extensions may not work.
    • Files can be recorded with a variety of fixed or variable bit rates. Song title, artist name, and album will be available for display by the radio when recorded using ID3 tags version 1 and 2.
    • 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.
    • Make sure to finalize the disc when burning an MP3/WMA disc, using multiple sessions. It is usually better to burn the disc all at once.

The player will be able to read and play a maximum of 50 folders, 5 sessions, and 999 files. Long file names, folder names may use more disc memory space than necessary. To conserve space on the disc, minimize the length of the file, folder names. You can also play an MP3/WMA CD that was recorded using no file folders. The system can support up to 8 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 50 folders, 5 sessions, and 999 files the player will let you access and navigate up to the maximum, but all items over the maximum will be ignored.

Root Directory

The root directory will be treated as a folder. If the root directory has compressed audio files, the directory will be displayed as ROOT. All files contained directly under the root directory will be accessed prior to any other directory.

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 will advance to the next folder in the file structure that contains compressed audio files and the empty folder will not be displayed or numbered.

No Folder

When the CD contains only compressed files, the files will be located under the root folder. The next and previous folder functions will have no function on a CD that was recorded without folders or playlists. When displaying the name of the folder the radio will display ROOT.

When the CD contains only compressed audio files, but no folders, all files will be located under the root folder. When the radio displays the name of the folder, the radio will display ROOT.

Order of Play

Tracks will be played in the following order:

    • Playback will begin from the first track under the root directory.
    • When all tracks from the root directory have been played, playback will continue from files, according to their numerical listing.
    • After playing the last track from the last folder, the player will begin playing again at the first track of the first folder or root directory.

File System and Naming

The song name in the ID3 tag will be displayed. If the song name is not present in the ID3 tag, then the radio will display the file name without the extension (such as MP3/WMA) instead.

Track names longer than 32 characters or 4 pages will be shortened. The display will not show parts of words on the last page of text and the extension of the filename will not be displayed.

Playing an MP3/WMA

With the ignition on, insert a CD partway into the slot, label side up. The player will pull it in, Loading, then Filecheck, and then MP3 or WMA will appear on the display. The CD should begin playing. You cannot insert a CD with the ACC off.

As each new track starts to play, the track number, and the song name will appear on the display.

If the ignition or radio is turned off with a CD in the player, it will stay in the player. When a CD is in the player and the ignition is turned on, the radio must be turned on before the CD will start playback. When the ignition and radio are turned on, the CD will start playing where it stopped, if it was the last selected audio source.

The CD player can play the smaller 3 inch (8 cm) single CDs with an adapter ring. Full-size CDs and the smaller CDs are loaded in the same manner.

If playing a CD-R, the sound quality may 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 may be an increase in skipping, difficulty in finding 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, see Care of Your CDs for more information.

If there is no apparent damage, try a known good CD.

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 instead.

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.

    • 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.
    • The format of the CD may not be compatible. See "MP3 Format" earlier in this section.
    • There may have been a problem while burning the CD.
    • The label may 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. If the radio displays an error message, write it down and provide it to your dealer when reporting the problem.
