Playing an MP3/WMA
While the ignition is on, insert a CD partway into
the slot, label side up. The player pulls it in,
Loading, then Filecheck, and then MP3 or WMA
displays. The CD should begin playing. A CD plays
only while the ignition is on or ACC (accessory).
As each new track starts to play, the track number,
and the song name displays.
If the ignition or radio is turned off with a CD in
the player, it stays in the player. When a CD is in
the player and the ignition is turned on, the
radio must be turned on before the CD starts
playback. When the ignition and radio are turned
on, the CD starts 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 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 does 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.
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.
Notice: If a label is added to a CD, or more
than one CD is inserted into the slot at a time,
or an attempt is made to play scratched or
damaged CDs, the CD player could be
damaged. While 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.
If an error displays, see "CD Messages" later in
this section.
