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.

:To view the next page.
:To return to the previous screen. When starting the navigation system, the
current position is displayed first.
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
map screen.
A street name will appear on the bottom of
the screen, depending on the scale of the
map (

You can return to this map screen that
shows your current position at any time
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.
