If an auxiliary input device is not

the DVD slot and the CD slot the
DVD/CD AUX button only cycles
between the two sources and
does not indicate No Aux Input
Device .
If a front auxiliary input device is
connected, the DVD/CD AUX
button cycles through all
available options.
If a disc is inserted into the top DVD
slot, the rear seat operator can turn
on the video screen and use the
remote control to only navigate
the CD tracks through the remote
control.

Care of CDs and DVDs
If playing a CD-R, the sound quality
can be reduced due to CD-R or
CD-RW quality, the method of
recording, the quality of the music
that has been recorded, and the
way the CD-R or CD-RW has been
handled. Handle them carefully.
Store CD-R(s) or CD-RW(s) in their
original cases or other protective
cases and away from direct sunlight
and dust. The CD or DVD 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.
