POSITIONING ADJUSTMENT
When the system judges that the vehicle posi-
tion information is not accurate based on vehicle
speed and gyro sensor data calculations, the
system will adjust the vehicle position informa-
tion using GPS signals.
RECEIVING SIGNALS FROM GPS
SATELLITES
Sometimes, satellite reception is weak. The fol-
lowing are places where signals tend to be
weak:
cInside tunnels and parking lots in buildings
cAreas with numerous tall buildings
cUnder multi-layered highways
cIn a dense forest
cNear military bases and certain government
facilities
Vehicles in these areas may not receive GPS
signals (Indicator color: gray) .INFO:
The antenna for GPS is located behind the in-
strument panel inside the vehicle.Do not place
any objects, especially mobile phones or
transceivers, on the instrument panel.Be-
cause the strength of the GPS signals are ap-
proximately one billionth of that of TV waves;
phones and transceivers will decrease the
strength or may totally disrupt the signals.DISPLAY OF GPS INFORMATION

Birdview™.This is because the displayed information is reduced so
that the screen does not become too crowded. There is
also a chance that names of roads or locations will be dis-
played twice. The name appearing on the screen may be
different because of a processing procedure.This should not be regarded as abnormal.

ample on a ferry boat or car transporter.Drive the vehicle with the GPS on for some distance.

ing the headlights on.When the lights were last turned on, the last setting was
