radio GMC SIERRA 2007 Workshop Manual

If a front auxiliary device is connected, the
DVD/CD AUX button cycles through all available
options, such as: DVD slot, CD slot, Front
Auxiliary, and Rear Auxiliary (if available). See
“Using the Auxiliary Input Jack(s)” later in
this section, or “Audio/Video (A/V) Jacks” under,
Rear Seat Entertainment System on page 355
for more information.
Using an MP3 (Radio with CD or
Six-Disc CD Player)
MP3/WMA CD-R or CD-RW Disc
The radio plays MP3/WMA les that were recorded
on a CD-R or CD-RW disc. The les can be
recorded with the following xed bit rates: 32 kbps,
40 kbps, 56 kbps, 64 kbps, 80 kbps, 96 kbps,
112 kbps, 128 kbps, 160 kbps, 192 kbps,
224 kbps, 256 kbps, and 320 kbps or a variable
bit rate. Song title, artist name, and album
are available for display by the radio when
recorded using ID3 tags version 1 and 2.
Compressed Audio
The radio also plays discs that contain both
uncompressed CD audio (.CDA les) and
MP3/WMA les. By default the radio shows the
MP3/WMA label on the left side of the screen but
plays both le formats in the order in which
they were recorded to the disc.
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 is able to read and play a
maximum of 50 folders, 15 playlists, and
a combined total of 512 folders and les.
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.
339

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.

button to advance playback quickly within an
MP3/WMA le. Sound is heard at a reduced
volume. Release this button to resume playing the
le. The elapsed time of the le displays.
RDM (Random):With the random setting,
MP3/WMA les on the CD-R or CD-RW can be
listened to in random, rather than sequential order,
on one CD-R or CD-RW, or all discs in a six-disc
CD player. To use random, do one of the following:
1. To play MP3/WMA les from the CD-R or
CD-RW in random order, press the pushbutton
positioned under the RDM label until Random

pushbutton again to turn off random play.
2. To play songs from all CDs loaded in a six-disc
CD player in random order, press the
pushbutton positioned under the RDM label
until Randomize All Discs displays. Press the
same pushbutton again to turn off random play.h(Music Navigator):Use the music navigator
feature to play MP3/WMA les on the CD-R or
CD-RW in order by artist or album. Press
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
les by that artist. To listen to MP3/WMA les
by another artist, press the pushbutton located
below either arrow button. The CD goes to
the next or previous artist in alphabetical order.
Continue pressing either button until the desired
artist is displayed.

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

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.
