Introduction
Thank you for your purchase of the Navigation System. Please read
this manual carefully to ensure proper use. Keep this manual in your
vehicle at all times.
The Navigation System is one of the most technologically advanced
vehicle accessories ever developed. The system receives satellite sig-
nals from the Global Positioning System (GPS) operated by the U.S.
Department of Defense. Using these signals and other vehicle sen-
sors, the system indicates your present position and assists in locating
a desired destination.
The navigation system is designed to select efficient routes from your
present starting location to your destination. The system is also designed
to direct you to a destination that is unfamiliar to you in an efficient manner.
The system uses DENSO maps. The calculated routes may not be the
shortest nor the least traffic congested. Your own personal local knowl-
edge or “short cut” may at times be faster than the calculated routes.
The navigation system’s database includes about 75 Point of Interest
categories to allow you to easily select destinations such as restaurants
and banks. If a destination is not in the database, you can enter the street
address or a major intersection close to it and the system will guide you
there.
The system will provide both a visual map and audio instructions. The au-
dio instructions will announce the distance remaining and the direction to
turn in approaching an intersection. These voice instructions will help you
keep your eyes on the road and are timed to provide enough time to allow
you to maneuver, change lanes or slow down.

Please be aware that all current vehicle navigation systems have
certain limitations that may affect their ability to perform properly.
The accuracy of the vehicle’s position depends on the satellite con-
dition, road configuration, vehicle condition or other circumstan-
ces. For more information on the limitations of the system, refer to
pages 138 through 139.

APPENDIX
138
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.
