Playing a CD
Insert a CD partway into the slot, label side up. The
player will pull it in and the CD should begin playing. The
CD symbol will appear on the display. If you want to
insert a CD with the ignition off, rst press the eject
button or the DISPL knob.

player, it will stay in the player. When you turn on
the ignition or the radio, the CD will start playing, where

As each new track starts to play, the track number will
appear on the display.
The CD player can play the smaller 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 nding 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.
Do not play 3 inch CDs without a standard adapter CD.

up to 30 to 45 minutes long on each side. Tapes longer
than that are so thin they may not work well in this player.
The longer side with the tape visible should face to the
right. If the ignition is on, but the radio is off, the tape can
be inserted and will begin playing. A tape symbol will
appear on the display whenever a tape is inserted. If you
