2007 GMC SIERRA CD player

Avoid subfolders. The system can support up to
eight subfolders deep, however, keep the total
number of folders to a minimum in order to
reduce the complexity and confusion in trying to
locate a particular folder during playback.
Make sure playlists have a .mp3 or .wpl
extension (other le extensions might
not work).
Minimize the length of the le, folder, or playlist
names. Long le, folder, or playlist names, or a
combination of a large number of les and
folders, or playlists can cause the player to be
unable to play up to the maximum number of
les, folders, playlists, or sessions. If you wish
to play a large number of les, folders, playlists
or sessions, minimize the length of the le,
folder, or playlist name. Long names also take
up more space on the display, potentially
getting cut off.
Finalize the audio disc before you burn it.
Trying to add music to an existing disc might
cause the disc not to function in the player.Playlists can be changed by using the previous
and next folder buttons, the tuner knob, or
the seek buttons. An MP3/WMA CD-R or CD-RW
that was recorded can also be played using no
le folders. If a CD-R or CD-RW contains
more than the maximum of 50 folders, 15 playlists,
and a combined total of 512 folders and les,
the player lets you access and navigate up to the
maximum, but all items over the maximum are
not accessible.
Root Directory
The root directory of the CD-R or CD-RW is
treated as a folder. If the root directory has
compressed audio les, the directory is displayed
as the CD label. All les contained directly
under the root directory are accessed prior to any
root directory folders. However, playlists (Px)
are always accessed before root folders or les.
If a disc contains both uncompressed CD
audio (.CDA) and MP3/WMA les, a folder under
the root directory called CD accesses all of
the CD audio tracks on the disc.
340

Empty Directory or Folder
If a root directory or a folder exists somewhere in
the le structure that contains only
folders/subfolders and no compressed les directly
beneath them, the player advances to the next
folder in the le structure that contains compressed
audio les. The empty folder does not display.
No Folder
When the CD-R or CD-RW contains only
compressed les, the les are located under the
root folder. The next and previous folder function
does not display on a CD-R or CD-RW that
was recorded without folders or playlists.
When the CD-R or CD-RW contains only playlists
and compressed audio les, but no folders, all les
are located under the root folder. The folder down
and the folder up buttons search playlists (Px) rst
and then goes to the root folder.
Order of Play
Tracks recorded to the CD-R or CD-RW are
played in the following order:
Play begins from the rst track in the rst
playlist and continues sequentially through
all tracks in each playlist. When the last track
of the last playlist has played, play continues
from the rst track of the rst playlist.
Play begins from the rst track in the rst
folder and continues sequentially through
all tracks in each folder. When the last track of
the last folder has played, play continues
from the rst track of the rst folder.
When play enters a new folder, the display does
not automatically show the new folder name unless
you have chosen the folder mode as the default
display. The new track name displays.
341

File System and Naming
The song name that displays is the song name
that is contained in the ID3 tag. If the song name is
not present in the ID3 tag, then the radio displays
the le name without the extension (such
as .mp3) as the track name.
Track names longer than 32 characters or
four pages are shortened. Parts of words on the
last page of text and the extension of the lename
does not display.
Preprogrammed Playlists
Preprogrammed playlists that were created using
WinAmp™, MusicMatch™, or Real Jukebox™
software can be accessed, however, they cannot
be edited using the radio. These playlists are
treated as special folders containing compressed
audio song les.
Playing an MP3/WMA
Insert a CD-R or CD-RW partway into the slot
(Single CD Player), or press the load button and
wait for the message to insert disc (Six-Disc
CD Player), label side up. The player pulls it in,
and the CD-R or CD-RW should begin playing.If the ignition or radio is turned off with a CD-R or
CD-RW in the player, it stays in the player.
When the ignition or radio is turned on, the CD-R
or CD-RW starts to play where it stopped, if it
was the last selected audio source.
As each new track starts to play, the track number
and song title displays.
If playing a CD-R or CD-RW, the sound quality
can be reduced due to CD-R or CD-RW quality,
the method of recording, the quality of the
music that has been recorded, and the way the
CD-R or CD-RW has been handled. There can be
an increase in skipping, difficulty in nding
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, seeCare of Your CDs and DVDs on
page 370for more information.

If there is no apparent damage, try a known
good CD.
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.
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.
If an error displays, see “CD Messages” later in
this section.

the pushbutton located below the music navigator
label. The player scans the disc to sort the les
by artist and album ID3 tag information. It
might take several minutes to scan the disc
depending on the number of MP3/WMA les
recorded to the CD-R or CD-RW. The radio can
begin playing while it is scanning the disc in
the background. When the scan is nished, the
CD-R or CD-RW begins playing again.
Once the disc has scanned, the player defaults to
playing MP3/WMA les in order by artist. The
current artist playing is shown on the second line
of the display between the arrows. Once all
songs by that artist are played, the player moves
to the next artist in alphabetical order on the
CD-R or CD-RW and begins playing MP3/WMA

MP3/WMA CD-R or CD-RW Disc
Compressed Audio or Mixed Mode Discs
The radio also plays discs that contain both
uncompressed CD audio (.CDA les) and
MP3/WMA les depending on which slot the disc
is loaded into. By default the radio reads only
the uncompressed audio (.CDA) and ignores the
MP3/WMA les on the DVD deck. On the CD
deck, pressing the CAT button toggles between
compressed and uncompressed audio format, the
default being the uncompressed format (.CDA).
345

MP3/WMA Format
If you burn your own MP3/WMA disc on a
personal computer:
Make sure the MP3/WMA les are recorded
on a CD-R or CD-RW disc.
Do not mix standard audio and MP3/WMA
les on one disc.
The CD player (lower slot) is able to read and
play a maximum combination of 512 les and
folders. The DVD player (upper slot) is able to
read 255 folders, 15 playlists and 40 sessions.
Create a folder structure that makes it easy to
nd songs while driving. Organize songs by
albums using one folder for each album.
Each folder or album should contain 18 songs
or less.
Avoid subfolders. The system can support up to
eight subfolders deep, however, keep the total
number of folders to a minimum in order to
reduce the complexity and confusion in trying to
locate a particular folder during playback.
Make sure playlists have a .m3u, .wpl
or .pls extension as other le extensions may
not work.
Minimize the length of the le, folder or playlist
names. Long le, folder, or playlist names, or a
combination of a large number of les and
folders, or playlists can cause the player to be
unable to play up to the maximum number of
les, folders, playlists, or sessions. If you wish
to play a large number of les, folders, playlists,
or sessions, minimize the length of the le,
folder, or playlist name. Long names also take
up more space on the display, potentially
getting cut off.
Finalize the audio disc before you burn it.
Trying to add music to an existing disc can
cause the disc not to function in the player.
Root Directory
The root directory of the CD-R or CD-RW is
treated as a folder. If the root directory has
compressed audio les, the directory is displayed
as F1 ROOT. All les contained directly under
the root directory are accessed prior to any root
directory folders. However, playlists (Px) are
always accessed before root folders or les.
346

Empty Directory or Folder
If a root directory or a folder exists somewhere in
the le structure that contains only
folders/subfolders and no compressed les directly
beneath them, the player advances to the next
folder in the le structure that contains compressed
audio les. The empty folder does not display.
No Folder
When the CD-R or CD-RW contains only
compressed les, the les are located under the
root folder. The next and previous folder function
does not function on a CD-R or CD-RW that was
recorded without folders or playlists. When
displaying the name of the folder the radio
displays ROOT.
When the CD-R or CD-RW contains only playlists
and compressed audio les, but no folders, all
les are located under the root folder. The folder
down and the folder up buttons search playlists
(Px) rst and then goes to the root folder.
When the radio displays the name of the folder
the radio displays ROOT.
Order of Play
Tracks recorded to the CD-R or CD-RW are
played in the following order:
Play begins from the rst track in the rst
playlist and continues sequentially through
all tracks in each playlist. When the last track
of the last playlist has played, play continues
from the rst track of the rst playlist.
Play begins from the rst track in the rst
folder and continues sequentially through
all tracks in each folder. When the last track of
the last folder has played, play continues
from the rst track of the rst folder.
When play enters a new folder, the display does
not automatically show the new folder name unless
the folder mode was chosen as the default
display. The new track name displays.
