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.

Radio Data System (RDS)

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

With RDS:

    • Stations can be selected based on programming.
    • Stations with traffic announcements can be selected.
    • Announcements concerning local and national emergencies can be received.
    • Messages display from radio stations.

RDS relies on receiving specific information from radio stations and only works when the information is available. In rare cases, a radio station could broadcast incorrect information that causes the radio features to work improperly. Contact the radio station if this happens.

When 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.

RDS Messages

ALERT: Displays when local or national emergency announcements are received. If the radio tunes to a related network station for the announcement, it returns to the original station when the announcement ends. The announcement should be heard even if the volume is low or a CD is playing. If a CD is playing, it will stop playing during the announcement.

    • The RDS alert feature is not supported by all RDS radio stations.
    • The RDS alert feature cannot be turned off.
    • Alert is not affected by tests of the emergency broadcast system.
MSG (Message): Displays if the current RDS station has a message. The message displays the artist, song title, call in phone numbers, etc. If the entire message does not display, parts of the message appear every three seconds until the message is completed. MSG disappears from the display once the completed message has displayed.

Radio Messages for XM Only

See XM Radio Messages later in this section for further detail.

TUNE ADJ: Turn the TUNE ADJ knob to select tracks on the CD.

SEEK TRACK : Press to go to the start of the current track, if more than ten seconds have played. Press to go to the next track. Holding or pressing or multiple times causes the player to continue moving backward or forward through the tracks on the CD.

EQ (Equalization): Press to select an equalization setting while playing a CD. See "EQ" listed previously for more information. If an EQ setting is selected for a CD, it is activated each time a CD is played.

Care of CDs

The sound quality of the CD player can be reduced because of:

    • The CD-R quality.
    • The method of recording the CD-R.
    • The quality of the music that has been recorded on the CD-R.
    • The way the CD-R has been handled.

Store CD-R(s) in their original cases or other protective cases and away from dust and direct sunlight. 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 may not play properly or 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.

To clean a CD, use a soft lint free cloth, or dampen a clean soft cloth in a mild neutral detergent solution mixed with water. Wipe the CD from the center to the edge.

Care of The CD Player

Use a marking pen to identify CDs, do not add labels.

Do not use CD lens cleaners; they could damage the CD player.

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.

Playing an MP3 CD-R Disc

Radios with the MP3 feature are capable of playing an MP3 CD-R disc. For more information on how to play an MP3 CD-R disc, see Using an MP3 later in this section.

CD Messages

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

    • The CD player is very hot. When the temperature returns to normal, the CD should play.
    • The road is very rough. 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 might not be compatible. See Using an MP3 later in this section.
    • A problem may have occurred while burning the CD.
    • The label could be caught in the CD player.

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 the Auxiliary Input Jack

The radio has an auxiliary input jack located on the lower right side of the faceplate. This is not an audio output; do not plug the headphone set into the front auxiliary input jack. An external audio device such as an iPod, laptop computer, MP3 player, CD changer, etc. can be connected to the auxiliary input jack for use as another audio source.

To use a portable audio player, connect a 3.5 mm (1/8 inch) cable to the radio's front auxiliary input jack. When a device is connected, press the radio CD/AUX button to begin playing audio from the device over the vehicle speakers.
