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. For details, refer to “Delay Power Off to
Accessories Until Exit,” under “Personal Settings (Cus-
tomer Programmable Features),” under “Electronic Ve-
hicle Information Center (EVIC)” in Section 4 of this
manual.

REC Setting the Clock
GPS Clock
The GPS receiver used in this system is synchronized to
the time data being transmitted by the GPS satellites. The
satellites’ clock is Greenwich Mean Time (GMT). This is
the worldwide standard for time. This makes the sys-
tem’s clock very accurate once the appropriate time zone
and daylight savings information is set.
