Press MODE (3) repeatedly to toggle
between the CD player and the optional
external sound source AUX, USB or the
optional Sirius satellite radio.
The currently selected sound source will be
shown in the display.
AUXThe AUX (auxiliary) port, located under the cen-
ter armrest, can be used to connect for exam-
ple, an MP3 player.
If the player is being charged through a 12-volt
socket while it is connect to the AUX port,
sound quality may be impaired.
The volume of the external sound source AUX
may be different from the volume of the internal
sound sources such as the CD player or the
radio. If the external sound source's volume is
too high, the quality of the sound may be
impaired.
This can be prevented by adjusting the external
sound source's input volume.
1. While playing the radio or a CD, lower the
audio volume to about one-quarter.
2.
Switch to
AUX mode on the audio system
by pressing the MODE button.
3. Connect the headphone output from your
music player to the AUX input using a cable
with a stereo 3.5 mm miniplug at both
ends.
4. Set your music player's headphone vol-
ume to three-quarters using the player's
volume controls.

Steering wheel keypad
The four buttons on the steering wheel keypad
can be used to control the audio system. The
steering wheel keypad can be used to adjust
volume, shift between preset stations and
change CD tracks. Press one of the two left-
hand buttons briefly to change to the next/pre-
vious preset radio station, or to go to the next/
previous track on a CD. Press and hold down
these buttons to search within a track on a CD.
Daytime/twilight displayIn daylight the information is displayed against
a light background. In darkness it is displayed
against a dark background.
USB/iPodŸŸ connector*
An auxiliary device, such as an iPodŸ, MP3
player or a USB flash drive can be connected
to the audio system via the connector in the
center console storage compartment. A stand-
ard cable from an iPodŸ or MP3 player can be
routed under the cover to the AUX connector
in the storage compartment.
A sound source must be chosen, depending on
the device that has been connected:
1.
Use MODE to select
iPod or USB. The textConnect device will be displayed.
2. Connect the device to the connector in the
center console storage compartment (see
the illustration).

The text LOADING will be displayed while the
system loads the files (folder structure) on the
device. This may take a short time.
When information about the files (the folder
structure) on the device has been loaded, the
resulting list includes information on the artist,
genre and song title.
To navigate in the folder structure, press
ENTER and scroll up and down the folders
using the arrow buttons (on the audio system
control panel or on the steering wheel keypad).
Press the right arrow button to select a folder.
Press the left arrow button to go up a level in
the folder structure. Press ENTER to go down
a level in the folder structure.
Tracks can be selected in two ways:

Turn the Tuning knob (no. 4 in the illustra-
tion on page 248) clockwise or counter-
clockwise.

Use the right or left arrow keys on the nav-
igation control (no. 5 in the illustration on
page 248) to select the desired track. The
arrow keys on the steering wheel keypad
can also be used in the same way.NOTE
The system supports playback of files in the
most common versions of formats such as
mp3, wma, and wav. However, there may be
versions of these formats that the system
does not support.
The system also supports a number of
iPod
Ÿ models produced in 2005 or later.
USB flash driveTo simplify the use of a USB flash drive, it is
advisable to only store music files on the drive.
It will take considerably longer for the system
to index the files on the drive if it contains any-
thing other than compatible music files.
NOTE
•The system supports removable media
that uses the USB 2.0 standard and the
FAT32 file system and can index up to
500 folders and a maximum of 64,000
files. The device must have at least 256
Mb of memory.
•When using a longer type of USB flash
drive, connecting it with a USB adapter
cable will help reduce mechanical wear
on the USB socket and the USB flash
drive.
MP3 playerMany MP3 players have a file indexing system
that is not supported by the vehicle's audio
system. In order to use an MP3 player, the sys-
tem must be set to USB Removable device/
Mass Storage Device.
iPodŸ
An iPodŸ receives current and its battery is
charged through the connecting cord. How-
ever, if the iPod's battery is completely
drained, it should be recharged before the
iPodŸ is connected to the audio system.
NOTE
When an iPodŸ is used as a sound source,
the vehicle's audio system has a menu
structure similar to the one in the iPod
Ÿ. See
the iPod's manual for detailed information.
For further information, refer to the accessory
manual USB/iPodŸ Music Interface.

sound reproduction through the use of digital
signal processing. This calibration takes into
account the speakers, amplifier, cabin acous-
tics, the seating position of the listener, etc., for
each combination of vehicle and audio system.
There is also dynamic calibration that takes
into account the setting of the volume control,
radio reception, and the vehicle's speed. The
sound settings described in this manual, such
as
BASS, TREBLE, and Equalizer front…/Equalizer rear… are only intended to enable
the user to adapt sound reproduction to his/her
personal preferences.

Introduction
Display when the radio is receiving an HD Radio
broadcast
HD radio is a brand name registered by the
Ibiquity digital corporation2. They are the
developer of a broadcasting technology called
IBOC or In Band On Channel, which refers to
the method of transmitting a digital radio
broadcast signal centered on the same fre-
quency as the AM or FM station's present fre-
quency.The IBOC system is referred to as a "hybrid"
since it is both analogue and digital. During
hybrid operation, receivers still continue to
receive the analogue (non-digital) signal. HD
radio receivers incorporate both modes of
reception, where the receiver will automatically
switch to the analogue signal if the digital signal
cannot be decoded or is lost by the receiver.
When you have tuned to an HD Radio station,
the
symbol will appear in the audio sys-
tem display.
More information about HD radio and IBOC
can be found on Ibiquity's website,
www.hdradio.com and www.ibiquity.com.
Benefits of digital broadcasting
•Better sound (FM sounds near CD quality
and AM as analogue FM).
•Some FM frequencies offer a greater num-
ber of listening choices through “multicast-
ing” (consisting of a frequency's main
channel and any sub-channels that may
also be available on that particular fre-
quency. See also the section "Sub-chan-
nels" below).
•When receiving a digital signal there is no
multipath disturbance or hisses/pops/
crackling due to outside influences.
How HD broadcasting worksHD Radio works similarly to conventional radio
and broadcasts of this type are available in
many areas of the United States. However,
there are a few key differences:
•Instead of transmitting one analogue sig-
nal, stations send out a bundled signal –
both analogue and digital.
•An HD radio receiver can receive both dig-
ital and analogue broadcasts. Depending
on the terrain and location of the vehicle
(which will influence the signal strength),
the receiver will determine which signal to
receive.
Limitations
•Main channel vs. sub-channels (FM
only): The main channel is the only channel
that can receive in hybrid mode (both dig-
ital and analogue). If a frequency has sub-
channels, they are broadcast in digital
mode only. The main FM channel will be
displayed as, for example, 93.9 WNYC
(Volvo uses the symbol > to indicate there
are sub-channels available) The sub-FM
