Playing a CD (Single CD Player)
Insert a CD partway into the slot, label side up. The
player pulls it in and the CD should begin playing.
If the ignition or radio is turned off with a CD in the
player, it stays in the player. When the ignition or radio
is turned on, the CD starts playing where it stopped, if it
was the last selected audio source.
When a CD is inserted, the CD symbol displays. As
each new track starts to play the track number displays.
Care of CDs
If playing a CD-R, the sound quality can 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. Handle them
carefully. Store CD-R(s) in their original cases or other
protective cases and away from direct sunlight and
dust. The CD player scans the bottom surface of the
disc. If the surface of a CD is damaged, such as
cracked, broken, or scratched, the CD does not play
properly or not at all. Do not touch the bottom side of a
CD while handling it; this could damage the surface.
Pick up CDs by grasping the outer edges or the edge of
the hole and the outer edge.

CD Messages
DISC ERROR: If this message displays and/or the CD
ejects, it could be for one of the following reasons:
.The radio system does not support the playlist
format, the compressed audio format, or the data
file format.
.It is very hot. When the temperature returns to
normal, the CD should play.
.You are driving on a very rough road. When the
road becomes smoother, the CD should play.
.The CD is dirty, scratched, wet, or upside down.
.The air is very humid. If so, wait about an hour and
try again.
.There could have been a problem while burning
the CD.
.The label could be caught in the CD player.
If the CD is not playing correctly, for any other reason,
try a known good CD.
If any error occurs repeatedly or if an error cannot be
corrected, contact your dealer. If the radio displays an
error message, write it down and provide it to your
dealer when reporting the problem.
Using the Auxiliary Input Jack
The radio system has an auxiliary input jack located
on the lower right side of the faceplate. This is not an
audio output; do not plug the headphone set into the
front auxiliary input jack. You can however, connect
an external audio device such as an iPod™, laptop
computer, MP3 player, CD changer, or cassette tape
player, etc. to the auxiliary input jack for use as another
source for audio listening.
Drivers are encouraged to set up any auxiliary device
while the vehicle is in P (Park). See Defensive Driving
on page 5‑2for more information on driver distraction.

Black plate (100,1)Cadillac DTS Owner Manual - 2011
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio's front auxiliary input
jack. When connecting an auxiliary device, the radio
automatically detects the device and“Aux Input Device”
displays. The device begins playing audio over the
vehicle speakers. If an auxiliary device has already
been connected, the device does not begin playing
audio until the radio's CD/AUX button is pressed.
O(Power/Volume): Turn to increase or decrease the
volume of the portable player. You might need to do
additional volume adjustments from the portable device.
BAND: Press to listen to the radio when a portable
audio device is playing. The portable audio device
continues playing, so you might want to stop it or power
it off.
CD/AUX (CD/Auxiliary): Press to play a CD when
a portable audio device is playing. Press again and
the system begins playing audio from the connected
portable audio player. If a portable audio player is not
connected, “No Aux Input Device Found” displays.
Using an MP3
MP3/WMA CD-R or CD-RW Disc
The radio plays MP3 and WMA files that were recorded
on a CD-R or CD-RW disc. The files can be recorded
with the following fixed 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 can display when files are recorded using
ID3 tags version 1 and 2.
Compressed Audio
The radio also plays discs that contain both
uncompressed CD audio (.CDA files) and MP3/WMA
files. By default the radio reads only the uncompressed
audio and ignores the MP3/WMA files. Pressing the
CAT button toggles between compressed and
uncompressed audio format.
MP3/WMA Format
If you burn your own MP3/WMA disc on a personal
computer:
.Make sure the MP3/WMA files are recorded on a
CD-R or CD-RW disc.
.Do not mix standard audio and MP3/WMA files on
one disc.
4-100
Black plate (101,1)Cadillac DTS Owner Manual - 2011
.The CD player is able to read and play a maximum
of 50 folders, 50 playlists, and 255 files.
.Create a folder structure that makes it easy to find
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 .m3u or .wpl extension
(other file extensions might not work).
.Minimize the length of the file, folder or playlist
names. Long file, folder, or playlist names, or a
combination of a large number of files and folders,
or playlists can cause the player to be unable to
play up to the maximum number of files, folders,
playlists, or sessions. If you wish to play a large
number of files, folders, playlists, or sessions,
minimize the length of the file, 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.Playlists can be changed by using the
S
candc Tfolder buttons, theaknob,
or the SEEK arrows. An MP3/WMA CD-R or CD-RW
that was recorded using no file folders can also be
played. If a CD-R or CD-RW contains more than the
maximum of 50 folders, 50 playlists, and 255 files,
the player lets you access and navigate up to the
maximum, but all items over the maximum cannot be
accessed.
Root Directory
The root directory of the CD-R or CD-RW is treated as a
folder. If the root directory has compressed audio files,
the directory displays as F1 ROOT. All files contained
directly under the root directory are accessed prior to
any root directory folders. However, playlists (Px) are
always accessed before root folders or files.
Empty Directory or Folder
If a root directory or a folder exists somewhere in the
file structure that contains only folders/subfolders and
no compressed files directly beneath them, the player
advances to the next folder in the file structure that
contains compressed audio files. The empty folder does
not display.
4-101
Black plate (102,1)Cadillac DTS Owner Manual - 2011
No Folder
When the CD contains only compressed files, the files
are located under the root folder. The next and previous
folder functions do not display 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 files, but no folders, all files are located under the
root folder. The folder down and the folder up buttons
search playlists (Px) first 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 play in the
following order:
.Play begins from the first track in the first playlist
and continues sequentially through all tracks in
each playlist. When the last track of the last playlist
has played, play continues from the first track of
the first playlist.
‐Playlists can be changed by pressing
the
S candc Tfolder buttons,
the
aknob, or the SEEK arrows.
.Play begins from the first track in the first folder
and continues sequentially through all tracks in
each folder. When the last track of the last folder
has played, play continues from the first track of
the first folder.
When play enters a new folder, the display does not
automatically show the new folder name unless the
folder mode has been 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 file
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 filename 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 files. Playlists must
have a file extension of PLS, M3U, or WPL.
Playlists can be changed by using the
S candc Tfolder buttons, theaknob,
or the SEEK arrows. Tracks cannot be changed.
