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:For vehicles not equipped with the Electronic
Vehicle Information Center (EVIC), the radio, steering
wheel radio controls (if equipped), and 6 disc CD/DVD
changer (if equipped) will remain active for 10 minutes
after the ignition switch is turned off. Opening either
front door will cancel this feature.

NOTE:For vehicles equipped with the Electronic Ve-
hicle Information Center (EVIC), the radio, steering
wheel radio controls (if equipped), and 6 disc CD/DVD
changer (if equipped) will remain active for up to 60
minutes after the ignition switch is turned off. Opening
either front door will cancel this feature. The time is
programmable through the Electronic Vehicle Informa-
tion Center (EVIC). Refer to“Delay Power Off to Acces-
sories Until Exit”under“Personal Settings (Customer
Programmable Features)”under“Electronic Vehicle In-
formation Center (EVIC)”in Section 4 of this manual for

turn identification, selection menus and instructions for
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.
Clock Setting Procedure
Refer to“Setting the Clock”under”System Settings”in
your Navigation User’s Manual for details about setting
the clock.
