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.
