•
If a car phone or cellular phone is used
near the GPS antenna, GPS reception may
be lost temporarily.
•
Do not cover the GPS antenna with spray
paint or car wax, because this may block
the reception of GPS signals. Snow
buildup can also degrade the signals, so
keep the antenna clear.
NOTE
If a GPS signal has not been received for a
long time, your vehicle’s actual position
and the current position mark on the map
may diverge considerably or may not be
updated. In such case, once GPS reception
is restored, accuracy will be recovered.
Conditions likely to cause noticeable
positioning errors
For various reasons, such as the state of the
road you are traveling on and the
reception status of the GPS signal, the
actual position of your vehicle may differ
from the position displayed on the map
screen.
If you make a slight turn.
