Introduction
This manual explains the operation of the Navigation System. Please read this
manual carefully to ensure proper use. Keep this manual in your vehicle at all
times.
The screen shots in this document and the actual screens of the navigation sys-
tem differ depending on whether the functions and/or a contract existed and the
map data available at the time of producing this document.
The Navigation System is one of the most technologically advanced vehicle ac-
cessories ever developed. The system receives satellite signals from the Global
Positioning System (GPS) operated by the U.S. Department of Defense. Using
these signals and other vehicle sensors, the system indicates your present posi-
tion 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. Map database
is made based on AISIN AW maps, whose information source comes from
NAVTEQ maps. The calculated routes may not be the shortest nor the least
traffic congested. Your own personal local knowledge or “short cut” may at
times be faster than the calculated routes.
The navigation system’s database includes Point of Interest categories to allow
you to easily select destinations such as restaurants and hotels. 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 audio
instructions will announce the distance remaining and the direction to turn
when 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 ma-
neuver, change lanes or slow down.
Please be aware that all current vehicle navigation systems have certain limita-
tions that may affect their ability to perform properly. The accuracy of the ve-
hicle’s position depends on satellite conditions, road configuration, vehicle
condition or other circumstances. For more information on the limitations of
the system, refer to pages 157 through 158.

5. GPS (GLOBAL POSITIONING SYSTEM)
1. LIMITATIONS OF THE NAVIGATION SYSTEM
The Global Positioning System (GPS)
developed and operated by the U.S. De-
partment of Defense provides an accu-
rate current position, normally using 4
or more satellites, and in some case 3
satellites. The GPS system has a certain
level of inaccuracy. While the naviga-
tion system will compensate for this
most of the time, occasional positioning
errors of up to 100 m (300 feet) can and
should be expected. Generally, position
errors will be corrected within a few
seconds.When the vehicle is receiving signals
from satellites, the “GPS” mark appears
at the top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position on the map screen. Tunnels, tall
buildings, trucks, or even the placement
of objects on the instrument panel may
obstruct 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.
This navigation system calculates
the current position using satellite
signals, various vehicle signals, map
data, etc. However, an accurate posi-
tion may not be shown depending on
satellite conditions, road configura-
tion, vehicle condition or other cir-
cumstances.
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.
