the center console bin. This is not an audio output;
do not plug the headphone set into the front auxiliary
input jack. An external audio device such as an iPod,
laptop computer, MP3 player, etc. can be connected to
the auxiliary input jack for use as another source for
audio listening.
Set up any auxiliary device while the vehicle is stopped.
SeeDefensive Driving on page 4-2for more information
on driver distraction.
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio’s front auxiliary input jack.

Using the Radio Controls to Connect
and Control Your iPod

knobs and display your iPod song information on
the radio’s display. To connect and control your iPod
using the radio controls, your vehicle must have a USB
port. If it does, it is located in the center console bin.
You will also need a special iPod connection cable that
can be purchased with your vehicle or may be available
after, from your dealer/retailer. See your dealer/retailer
for more information.
This feature supports the following iPod models:
Fifth generation or later iPod
First or Second generation or later iPod Nano*
* For proper operation, make sure your iPod has the
latest rmware from Apple
®. Your iPod rmware can
be updated using the latest iTunes application.
See www.apple.com/itunes.
3-104

To connect and control your iPod, connect one end of
the specially purchased iPod connection cable to
the iPod’s dock connector. Connect the other end to
both the USB port and the auxiliary input jack. The USB
port and the auxiliary input jack are located in the
center console bin. If the vehicle is on and the USB
connection works, you will see a GM logo appear
on your iPod. Your iPod music will display on your
radio’s display and begin playing through your vehicle
radio system.
A standard iPod USB cable, like the one that came with
your iPod, cannot be used to connect an iPod to your
vehicle. You must use the iPod connection cable
that was purchased with your vehicle or that was made
available from your dealer/retailer in order for this
feature to work.
Use the radio Menu/Select knob to bring up the iPod
Menu and select Songs, Artists, Albums, Playlists
and Audio books to play from your iPod.Your iPod will charge while it is connected to
your vehicle and if your vehicle is turned to ACC/
ACCESSORY or ON/RUN. It can also be left connected
to your vehicle while the vehicle is turned off or removed.
With the vehicle turned off, the iPod will automatically be
powered off and will not charge or draw power from the
vehicle’s battery.
If you have an older iPod model that is not supported or
do not have the special iPod connection cable, you
can still listen to your iPod in your vehicle by connecting
it to the Auxiliary Input Jack using a standard 3.5 mm
(1/8 inch) stereo cable. See “Using the Auxiliary
Input Jack” earlier for more information.
Press the AM/FM, XM or HDD buttons to listen to one
of these sources while an iPod is connected. If a disc is
inserted, press the CD/AUX button to listen to a CD
or DVD-A disc. Press the CD/AUX button again to start
playing and controlling the connected iPod.
To properly dismount the iPod USB device before
disconnecting from the vehicle, press the button directly
under the EJECT label found on the iPod playback
screen.

Using an MP3
MP3/WMA Format
The Single CD and the Six-Disc CD Radio will play
MP3/WMA les that were recorded on a CD-R or
CD-RW disc. The HDD Radio is similar and can also
play MP3/WMA les recorded on DVD +/−R discs or a
USB storage device.
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 can display when les
are recorded using ID3 tags version 1 and 2.
Creating an MP3/WMA Disc
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.
Make sure the CD does not have more than a
maximum of 50 folders and playlists, and 255 les to
read and play.
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, keep the total number of
folders to a minimum to reduce the complexity and
confusion during playback.
Make sure playlists have a .mp3 or .wpl extension
(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.
Finalize the audio disc before burning it. Adding
music to an existing disc can cause the disc not
to function.
