formats: DVD - Video, DVD - Video (DTS),
DVD - Audio, CD - Digital Audio (CD - DA), CD-DA

and CDRW. The system may also play DVD - R
and DVD - RW type discs depending on the writing
software used. The system will 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.
