Foreword
Thank you for your purchase of the Navigation System. Please
read this manual carefully to ensure proper use. Keep this
manual stored in your vehicle at all times.
The Toyota Navigation System is one of the most technologically
advanced vehicle accessories ever developed. The system receives
satellite signals from the Global Po sitioning System (GPS) operated
by the U. S. Department of Defense. Using these signals and other
vehicle sensors, the system ca n show you where you are and
assist you 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
designed to direct you to a destinat ion that is unfamiliar to you in
an efficient manner. The system uses the maps of DENSO. The
calculated routes are neither the shortest routes nor routes without
traffic congestion. Your own personal local knowledge or “short cut”
may at times be faster than the calculated routes.
The navigation system’s database in cludes about 50 point of inter-
est categories to allow you to easily select destinations such as
restaurants and hotels. If a destinat ion is not in the database, you
can enter the street address or a ma jor intersection close to it and
the system will route you there. The system will provide both a
visual map and audio instructions. The audio instructions will an-
nounce the distance and direction to go when you are approaching
a fork or 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 condition, road conf iguration, vehicle condition or
other circumstances. For more information on the limitations
of the system, refer to pages 59 through 60.
BASIC FUNCTIONS
59
This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, an 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 built in for security reasons.
While the navigation system will compen-
sate for this most of the time, occasional
positioning errors of up to 300 feet (100 m)
can and should be expected. Generally,
position errors will be corrected within a
few seconds.
When your vehicle is not receiving signals
from the satellites, the “GPS” mark does
not appear at 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 good 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.
