This screen displays the current vehicle
position and a map of the surrounding local
area.
The current vehicle position mark (1) ap-
pears in the center or bottom center of the

from any screen by pushing the “MAP/
VOICE” button.
While driving, the current vehicle position
mark is fixed on the screen and the map
moves.
The current position is automatically set as
the vehicle receives signals from the GPS
(Global Positioning System). If the current
position is not correct, it is automatically
corrected after the vehicle receives sig-
nals from the GPS.
INFORMATION
D After battery disconnection, or on
a new vehicle, the current position
may not be correct. As soon as the
system receives signals from the
GPS, the correct current position
is displayed.
D To correct the current position
manually, see page 112.

APPENDIX

This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, the accurate posi-
tion may not be shown depending on
the satellite condition, road configura-
tion, vehicle condition or other circum-
stances.
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate cur-
rent vehicle position, normally using 4 or
more satellites, and in some cases 3 satel-
lites. The GPS system has a certain level
of inaccuracy. While the navigation sys-
tem will compensate for this most of the
time, occasional positioning errors of up to
300 feet (100 m) can and should be expec-
ted. Generally, position errors will be cor-
rected within a few seconds.
When your vehicle is receiving signals
from the satellites, the “GPS” mark ap-
pears at the top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position on the map display. Tunnels, tall
buildings, trucks, or even the placement of
objects on the instrument panel may ob-
struct the GPS signals.
The GPS satellites may not send signals
due to repairs or improvements being
made to them.
Even when the navigation system is re-
ceiving clear GPS signals, the vehicle
position may not be shown accurately or
inappropriate route guidance may occur in
some cases.
NOTICE
The installation of window tinting
may obstruct the GPS signals. Most
window tinting contains some metal-
lic content that will interfere with GPS
signal reception of the antenna in the
instrument panel. We advise against
the use of window tinting on vehicles
equipped with navigation systems.
