GMC 2007 Automobile User Manual


 
Playing an MP3/WMA
With the ignition on, insert a CD partway into the
slot, label side up. The player pulls it in, Loading,
then Filecheck, and then MP3 or WMA appears on
the display. The CD should begin playing. You
cannot insert a CD with the ACC (accessory) off.
As each new track starts to play, the track number,
and the song name appears on the display.
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 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.
There may 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 217
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 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.
If an error appears on the display, see “CD
Messages” later in this section.
