This system can play different types of media formats: DVD - Video, DVD - Video (DTS), DVD - Audio, CD - Digital Audio (CD - DA), CD-DA (DTS), CD - Text, CD - Extra, MP3 - CD, CDR, and CDRW. The system may also play DVD - R and DVD - RW type discs depending on the writing software used. The system may play DTS and Dolby tracks in surround sound.

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" in the Index of your vehicle's owner manual.

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

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.

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 soft marker instead.

Six-Disc DVD Changer Errors

Although the DVD or CD you are playing meets regulation requirements, there are circumstances that may cause the disc to not play correctly. Some of those circumstances may include the recording conditions of the disc, the disc condition, and the pick up circumstances of the player.

If using the system in extremely low or high temperatures, the video playback may become distorted.

Because of some types of compression techniques used during recording MP3 discs, the sound quality of the discs can be inferior. This is not caused by the audio system.
