Playing a CD
If the ignition or radio is turned off with the CD in the
player, it will stay in the player. When the ignition or the
radio is turned on, the CD will start playing, where it
stopped, if it was the last selected audio source.
The CD player can play the smaller 3 inch (8 cm) single
CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.
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. You may experience an
increase in skipping, difficulty in finding tracks, and/or
difficulty in loading and ejecting. If these problems occur
try a known good CD.
Do not add paper labels to CDs, they could get caught
in the CD player.
If an error appears on the display, see "CD Messages"
later in this section.
