selecting a variety of destinations and routes. The unit
also provides an AM/FM stereo radio and six-disc CD
changer with MP3 capability.
Mapping information for navigation is supplied on a
DVD that is loaded into the unit. One map DVD covers
all of North America. Refer to your “Navigation User’s
Manual” for detailed operating instructions.
REMOTE SOUND SYSTEM CONTROLS
The remote sound system controls are located on the
surface of the steering wheel at the 3 and 9 o’clock
positions.
Some models feature an Electronic Vehicle Information
Center (EVIC) with driver-interactive display. It is lo-
cated in the instrument cluster below the speedometer.
The audio mode of the EVIC can display any one of
twelve radio station preset frequencies, CD disc number,
CD track number, tape, or one of 200 Satellite radio
channels depending on which radio is in the vehicle.The VOLUME switch controls the volume of
the sound system. Pressing the top of the
rocker switch will increase the volume and
pressing the bottom of the rocker switch will
decrease the volume.
The AUDIO MODE SELECT button changes
the mode of the radio from AM to FM to Tape
to CD, or to Satellite (SAT) depending on
which radio is in the vehicle.

RADIO GENERAL INFORMATION
Radio Broadcast Signals
Your new radio will provide excellent reception under
most operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration and natural phenomena, which might lead you to
believe your sound system is malfunctioning. To help
you understand and save you concern about these “ap-
parent” malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:On vehicles so equipped the radio, steering
wheel radio controls and 6 disc CD/DVD changer if
equipped, will remain active for 10 minutes after the
ignition has been turned off, and the driver door has not
been opened. This feature is programmable through the
electronic vehicle information center (EVIC) — if
equipped. Refer to “Delay Power Off to Accessories Until
Exit” under “Personal Settings” in the Electronic Vehicle
Information Center section for details.
