Playing an MP3
Insert a CD-R partway into the slot (Single CD
Player), or press the load button and wait for the
message to insert disc (Six-Disc CD Player),
label side up. The player pulls it in, and the
CD-R should begin playing.
If the ignition or radio is turned off with a CD-R
in the player, it stays in the player. When the
ignition or radio is turned on, the CD-R starts to
play where it stopped, if it was the last selected
audio source.
As each new track starts to play, the track number
and song title displays.
The CD player can play the smaller 3 inch (8 cm)
single CD-Rs with an adapter ring. Full-size CD-Rs
and the smaller CD-Rs 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 will
not play properly. If the surface of the CD is soiled,
see Care of Your CDs on page 216 for more
information.
If there is no apparent damage, try a known
good CD.
Notice: If you add any label to a CD, insert
more than one CD into the slot at a time, or
attempt to play scratched or damaged CDs, you
could damage the CD player. When 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
marking pen.
If an error displays, see "CD Messages" later in
this section.
