GMC 2006 Sierra - Manual (Page 261)

Playing a CD
Insert a CD part way into the slot, label side up. The
player will pull it in and the CD should begin playing. If
you want to insert a CD with the ignition off, first press
the eject button or the INFO knob.
If the ignition or radio is turned off with the CD in the
player, it will stay in the player. When the ignition or radio
is turned on, the CD will start playing where it stopped, if it
was the last selected audio source.
When a CD is inserted, the CD symbol will appear on
the display. As each new track starts to play, the track
number will appear on the display.
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 and DVDs on page 3-132 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 instead.
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.
