United States shown, Canada similar


Object Number: 988558  Size: B3

If your vehicle has the Monsoon audio system, included are eight speakers and an eight channel amplifier. The radio displays MONSOON when the radio or the ignition is turned on. See your dealer/retailer for details.

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 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 appear on the 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 Canada. XM™ offers a large variety of coast-to-coast channels including music, news, sports, talk, traffic/weather (U.S. subscribers), and children’s programming. XM™ provides digital quality audio and text information that includes song title and artist name. A service fee is required in order to receive the XM™ service. For more information, contact XM™; In the U.S. at www.xmradio.com or call 1-800-852-XMXM (9696) or in Canada at www.xmradio.ca or call 1-877-GET-XMSR (438-9677).

Playing the Radio

DISP (Display): Press this knob to switch the display between the time and the temperature or the radio station frequency and the temperature. When the ignition is off, press this knob to display the time. For RDS, press this knob to change what appears on the display while using RDS. The display options are station name, RDS station frequency, PTY, and the name of the program (if available). For XM™ (if equipped), press this knob while in XM mode to retrieve four different categories of information related to the current song or channel: Artist, Song Title, Category or PTY, Channel Number/Channel Name. To change the default on the display, press the DISP knob until you see the desired display, then hold the knob for two seconds. The radio produces a beep and the selected display is now the default.

Playing a CD

Insert a CD partway into the slot, label side up. The player pulls it in and the CD should begin playing. If you want to insert a CD with the ignition off, first press the eject button or the DISP (display) knob.

As each new track starts to play, the track number displays.

If the ignition or radio is turned off with a CD in the player, it stays in the player. When the ignition or radio is turned on, the CD starts 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 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 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 does 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.

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.

(Reverse): Press and hold the pushbutton to reverse quickly within a track. You will hear sound at a reduced volume. Release the button to play the passage. The elapsed time of the track displays.

RDM (Random): Press this button to hear the tracks in random, rather than sequential, order. T#, RANDOM, and RDM displays. T and the track number displays when each track starts to play. Press RDM again to turn off random play. RANDOM OFF displays and RDM disappears from the display.

SEEK : Press the down SEEK arrow to go to the start of the current track if more than eight seconds have played. If this arrow is pressed more than once, the player continues moving backward through the CD. Press the up SEEK arrow to go to the start of the next track. If this arrow is pressed more than once, the player continues moving forward through the CD. If either the down or up SEEK arrow is held or pressed for more than two seconds, the CD enters CD scan mode and the CD plays the first 10 seconds of each track. Press either the down or up SEEK arrow again to stop scanning.

DISP (Display): Press this knob to see how long the current track has been playing. T, the track number, and the elapsed time of the track displays. To change the default on the display, time or elapsed time, press the knob until you see the desired display, then hold the knob for two seconds. The radio produces one beep and the selected display is now the default. Pressing this button also displays text on commercially recorded CDs (if available).

AUTO TONE/AUTO EQ (Automatic Equalization): Press this button to select the desired equalization setting while playing a CD. The equalization is automatically recalled when a CD is played. For more information, see AUTO TONE/AUTO EQ listed previously in this section.

BAND: Press this button to listen to the radio while a CD is playing. The inactive CD remains inside the radio for future listening.

SRCE (Source): Press this button to play a CD or to access a remote device (if installed) while listening to the radio.

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.
