2007 CHEVROLET COBALT audio

Compressed Audio
The radio also plays discs that contain both
uncompressed CD audio (.CDA les) and
MP3 les. By default the radio reads only the
uncompressed audio and ignores the MP3 les.
Pressing the CAT (category) button toggles
between compressed and uncompressed
audio format.
MP3 Format
If you burn your own MP3 disc on a personal
computer:
Make sure the MP3 les are recorded on a
CD-R or CD-RW disc.
Avoid mixing standard audio and MP3 les
on one disc.
The CD player is able to read and play a
maximum of 50 folders, 50 playlists, and
255 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.
Avoid subfolders. The system can support up
to 8 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, and might not fully display.
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.
Change playlists by using the previous and next
folder buttons, the tuner knob, or the seek buttons.
An MP3 CD-R or CD-RW that was recorded
using no le folders can also be played.
213

If a CD-R or CD-RW contains more than the
maximum of 50 folders, 50 playlists, and 255 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 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.
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
functions are not displayed 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.
214

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.
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 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.
The CD player can play the smaller 3 inch (8 cm)
single CD-Rs or CD-RWs with an adapter ring.
Full-size CD-Rs/CD-RWs and the smaller
CD-Rs/CD-RWs are loaded in the same manner.
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 on
page 224for 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.
216

Once the disc has been 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/
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. The CD goes to the next or previous artist in
alphabetical order. Continue pressing either button
until the desired artist displays.
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 album button. Press the
pushbutton below the back label to return to the
main music navigator screen. The album name
displays on the second line between the arrows and
songs from the current album and begins to play.Once all songs from that album are played, the
player moves to the next album in alphabetical
order on the CD-R or CD-RW and begins playing
MP3 les from that album.
To exit music navigator mode, press the
pushbutton below the Back label to return to
normal MP3 playback.
BAND:Press this button to listen to the radio
while a CD is playing. The CD remains inside the
radio for future listening.
CD/AUX (CD/Auxiliary):Press this button to
play a CD while listening to the radio. The CD icon
and a message showing disc and/or track number
displays while 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 Aux Input Device” displays.
