Radio Data System (RDS)

The audio system has a Radio Data System (RDS). RDS features are available for use only on FM stations that broadcast RDS information.

With RDS, the radio can do the following:

    • Seek to stations broadcasting the selected type of programming
    • Receive announcements concerning local and national emergencies
    • Display messages from radio stations
    • Seek to stations with traffic announcements

This system relies upon receiving specific information from these stations and will only work when the information is available. In rare cases, a radio station may broadcast incorrect information that will cause the radio features to work improperly. If this happens, contact the radio station.

While the radio is tuned to an RDS station, the station name or call letters will appear on the display instead of the frequency. RDS stations may also provide the time of day, a program type (PTY) for current programming, and the name of the program being broadcast.

You will hear the announcement, even if the volume is low or a CD is playing. If a CD is playing, play will stop during the announcement. Alert announcements cannot be turned off. If the radio tunes to a related network station for the announcement, it will return to the original station when the announcement is finished. ALERT will not be affected by tests of the emergency broadcast system. This feature is not supported by all RDS stations.

MSG (Message): If the current RDS station has a message, MSG will appear on the display. The message may display the artist, song title, call in phone numbers, etc. If the entire message does not appear on the display, parts of the message will appear every three seconds until the message is completed.

Using an MP3 CD

MP3 Format

This MP3 player will accept MP3 files that were recorded on an up to 700 MB CD-R CD. The files can be recorded with the following fixed 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 will be available when recorded using ID3 tags versions 1 and 2.

The player will be able to read and play a maximum of 50 folders, 50 playlists, 10 sessions, and 255 files. Long file, folder, or playlist names or a combination of a large number of files and folders or playlists may cause the player to be unable to play up to the maximum number of files, folders, playlists, or sessions. If you wish to play large numbers of files, folders, playlists or sessions minimize the length of the file, folder or playlist name. You can also play an MP3 CD that was recorded using no file folders. 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 50 folders, 50 playlists, 10 sessions, and 255 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 F1 ROOT. All files contained directly under the root directory will be accessed prior to any root directory folders. However, playlists (Px) will always be 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 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 playlists and compressed audio files, but no folders, all files will be located under the root folder. The folder down and the folder up buttons will search playlists (Px) first and then go to 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:

    • Play will begin from the first track in the first playlist and will continue sequentially through all tracks in each playlist. When the last track of the last playlist has been played, play will continue from the first track of the first playlist.
    • If the CD does not contain any playlists, then play will begin from the first track under the root directory. When all tracks from the root directory have been played, play will continue from files according to their numerical listing. After playing the last track from the last folder, play will begin again at the first track of the first folder or root directory.

When play enters a new folder, the display will not automatically show the new folder name. The new track name will appear on the display.

File System and Naming

The song name that will be displayed will be the song name that is contained in the ID3 tag. 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) as the track name.

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.

Preprogrammed Playlists

You can access preprogrammed playlists which were created by WinAmp™, MusicMatch™, or Real Jukebox™ software, however, you will not have editing capability. These playlists will be treated as special folders containing compressed audio song files.

Playing an MP3

Insert a CD partway into the slot, label side up. The player will pull it in, and LOADING CD will appear on the display. The CD should begin playing and the CD symbol will appear on the display. If the ignition and the radio are on, the CD will begin playing. A CD may be loaded with the radio off, but it will not start playing until the radio is on.

If the ignition or radio is turned off with a CD in the player it will stay in the player. When the ignition or radio is turned on, the CD will start to play where it stopped, if it was the last selected audio source.

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

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, try a known good CD.

CD Messages

If the CD comes out, it could be for one of the following reasons:

    • If it is very hot. When the temperature returns to normal, the CD should play.
    • If 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 GM dealer. If the radio displays an error message, write it down and provide it to your GM dealer when reporting the problem.
