audio GMC SIERRA 2008 Owner's Guide

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 could 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 could cause the disc
not to function in the player.
Playlists can be changed by using the
Sc
(previous) andcT(next) folder buttons, thef
knob, or the©SEEK¨arrows. You can also play an
MP3 CD-R or CD-RW that was recorded using no le
folders. If a CD-R or CD-RW contains more than
the maximum of 50 folders, 15 playlists, and 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 displays 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 les, a folder under the root directory called
CD accesses all of the CD audio tracks on the disc.
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 contains only compressed les, the les
are located under the root folder. The next and previous
folder function does not display on a CD that was
recorded without folders or playlists.
3-103

When the CD contains only playlists and compressed
audio les, but no folders, all les are located under the
root folder. The folder down and 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.
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
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.
ZEJECT:Press this button to eject CD-R(s) or
CD-RW(s). To eject the CD-R or CD-RW that is currently

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 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 les by that
artist. If you want to listen to MP3 les by another artist,
press the pushbutton located below either arrow button.
You will go to the next or previous artist in alphabetical
order. Continue pressing either button until the desired
artist is displayed.
To change from playback by artist to playback by album,
press the pushbutton located below the Sort By label.
From the sort screen, push one of the buttons below the

when a CD is in the player. Press this button again and
the system automatically searches for an auxiliary
input device such as a portable audio player. If a
portable audio player is not connected, “No Input Device
Found” displays.
Using an MP3 (Radio with CD and
DVD Player)
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, press the CAT (category) button to toggle between
compressed and uncompressed audio format, the default
being the uncompressed format (.CDA).
3-106

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 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 could 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 could 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.
3-107

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 contains only compressed les, the les
are located under the root folder. The next and previous
folder function does not function on a CD that was
recorded without folders or playlists. When displaying
the name of the folder the radio displays ROOT.
When the CD 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
you have chosen the folder mode as the default display.
The new track name displays.
File System and Naming
The song name that is displayed 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 displays.

Rear Seat Entertainment (RSE)
System
Your vehicle may have a DVD Rear Seat Entertainment
(RSE) system. The RSE system works with the
vehicle’s audio system. The DVD player is part of the
front radio. The RSE system includes a radio with a DVD
player, a video display screen, audio/video jacks, two
wireless headphones, and a remote control. See
Radio(s) on page 3-84for more information on the
vehicle’s audio/DVD system.
Before You Drive
The RSE is designed for rear seat passengers only.
The driver cannot safely view the video screen
while driving and should not try to do so.
In severe or extreme weather conditions the RSE
system might not work until the temperature is within
the operating range. The operating range for the
RSE system is above−4°F (−20°C) or below
140°F (60°C). If the temperature of your vehicle is
outside of this range, heat or cool the vehicle until the
temperature is within the operating range of the
RSE system.
Parental Control
The RSE system may have a Parental Control feature,
depending on which radio you have. To start Parental
Control, press and hold the radio power button for more
than two seconds to stop all system features such
as: radio, video screen, RSA, DVD and/or CD. While
Parental Control is on, a padlock icon displays.
The radio can be turned back on with a single press of
the power button, but the RSE system will remain
under Parental Control.
To turn Parental Control off, press and hold the radio
power button for more than two seconds. The RSE
returns from where it was previously left and the padlock
icon disappears from the radio display.
Parental Control can also be turned off by inserting or
ejecting any disc, pressing the play icon on the
radio DVD display menu, or changing an ignition
position.

Headphones
The RSE includes two 2-channel wireless headphones
that are dedicated to this system. Channel 1 is
dedicated to the video screen, while Channel 2 is
dedicated to RSA selections. These headphones can
used to listen to the radio, CDs, DVDs, MP3s, DVDAs,
any auxiliary source connected to A/V jacks, or the
auxiliary input jack, if your vehicle has this feature. The
wireless headphones have an On/Off button, channel
1/2 switch, and a volume control.Push the power button to turn on the headphones. An
indicator light located on the headphones comes
on. If the light comes on but, there is intermittent sound
and/or static on the headphones, or if the indicator
light does not come on, the batteries might need to be
replaced. See “Battery Replacement” later in this
section for more information. Switch the headphones to
Off when not in use.
Infrared transmitters are located at the rear of the
overhead console. The headphones shut off
automatically to save the battery power if the RSE
system and RSA are shut off or if the headphones are
out of range of the transmitters for more than
three minutes. If you move too far forward or step out of
the vehicle, the headphones lose the audio signal.
The headphones automatically turns off after four hours
of continuous use.
To adjust the volume on the headphones, use the
volume control located on the right side.
For optimal audio performance, the headphones must
be worn correctly. The symbol L (Left) appears on
the upper left side, above the ear pad and should be
positioned on the left ear. The symbol R (Right) appears
on the upper right side, above the ear pad and should
be positioned on the right ear.
