Base Radio with Six-Disc CD Shown, Bose® Similar


Object Number: 1411837  Size: B3

If your vehicle has the Bose® audio system, it has six Bose® amplified speakers.

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

This system relies upon receiving specific information from these stations and only works when the information is available. In rare cases, a radio station can broadcast incorrect information that causes 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 display instead of the frequency. RDS stations can also provide the time of day, a program type (PTY) for current programming, and the name of the program being broadcast.

XM™ Satellite Radio Service

XM™ is a satellite radio service that is based in the 48 contiguous United States and 10 Canadian provinces. XM™ Satellite Radio has a wide variety of programming and commercial-free music, coast-to-coast, and in digital-quality sound. During your trial or when you subscribe, you will get unlimited access to XM™ Radio Online for when you are not in your vehicle. A service fee is required to receive the XM™ service. For more information, contact XM™ at www.xmradio.com or call 1-800-929-2100 in the U.S. and www.xmradio.ca or call 1-877-438-9677 in Canada.

Care of Your CDs

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. Handle them carefully. Store CD-R(s) in their original cases or other protective cases and away from direct sunlight and dust. The CD player scans the bottom surface of the disc. If the surface of a CD is damaged, such as cracked, broken, or scratched, the CD does not play properly or not at all. Do not touch the bottom side of a CD while handling it; this could damage the surface. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge.

If the surface of a CD is soiled, take a soft, lint free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water, and clean it. Make sure the wiping process starts from the center to the edge.

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

Care of Your CD Player

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.

The use of CD lens cleaners for CDs is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD player mechanism.

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 displays, see "CD Messages" later in this section.

Using Song List Mode

The six-disc CD changer has a feature called song list. This feature is capable of saving 20 track selections.

To save tracks into the song list feature, perform the following steps:

  1. Turn the CD player on and load it with at least one CD. See "LOAD CD" listed previously in this section for more information.
  2. Check to see that the CD changer is not in song list mode. S-LIST should not display. If S-LIST displays, press the SONG LIST button to turn it off.
  3. Select the desired CD by pressing the numbered pushbutton and then use the right SEEK or TYPE arrows to locate the track to be saved. The track begins to play.
  4. Press and hold the SONG LIST button to save the track into memory. When SONG LIST is pressed, one beep sounds. After two seconds of continuously pressing the SONG LIST button, two beeps sound to confirm the track has been saved.
  5. Repeat Steps 3 and 4 for saving other selections.

S-LIST FULL displays if more than 20 selections are saved.

To play the song list, press the SONG LIST button. One beep sounds and S-LIST displays. The recorded tracks begin to play in the order they were saved.

Seek through the song list by using the SEEK arrows or the TYPE arrows. Seeking past the last saved track returns to the first saved track.

To delete tracks from the song list, perform the following steps:

  1. Turn the CD player on.
  2. Press the SONG LIST button to turn song list on. S-LIST displays.
  3. Press the SEEK arrows or the TYPE arrows to select the desired track to be deleted.
  4. Press and hold the SONG LIST button for two seconds. When SONG LIST is pressed, one beep sounds. After two seconds of continuously pressing the SONG LIST button, two beeps sound to confirm that the track has been deleted.

After a track has been deleted, the remaining tracks are moved up the list. When another track is added to the song list, the track is added to the end of the list.

To delete the entire song list, perform the following steps:

  1. Turn the CD player on.
  2. Press the SONG LIST button to turn song list on. S-LIST displays.
  3. Press and hold the SONG LIST button for more than four seconds. One beep sounds, followed by two beeps after two seconds, and a final beep sounds after four seconds. S-LIST EMPTY displays indicating the song list has been deleted.

If a CD is ejected, and the song list contains saved tracks from that CD, those tracks are automatically deleted from the song list. Any tracks saved to the song list again are added to the bottom of the list.

To end song list mode, press the SONG LIST button. One beep sounds and S-LIST is removed from the display.

CD Messages

CHECK CD:  If this 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.
    • 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.
