sat nav TOYOTA AVALON 2007 XX30 / 3.G Navigation Manual

i
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 Positioning System (GPS) operated by the U. S. Department of Defense. Using these signals and other
vehicle sensors, the system can 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 destination that is unfamiliar to you in an efficient manner. The system uses the maps of DENSO based on
NAVTEQ maps, GDT maps and infoUSA POIs. The calculated routes are neither the shortest routes nor routes without traffic conges-
tion. Your own personal local knowledge or “short cut” may at times be faster than the calculated routes.
The navigation system’s database includes about 50 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 route you there. The system will provide both a visual map and audio instructions. The audio instructions will announce
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 configuration, vehicle condition or
other circumstances. For more information on the limitations of the system, refer to pages lii through liv.

3. When there are 2 map screens dis-
played to switch the Northup/Head-
ingup of the right screen map, se-
lect the
“Right screen” switch.
4. Select the “Map orient.” of the
“Edit right screen”, and then the
Northup/Headingup of the right
screen is switched.
When 2 map screens are displayed, you
can set one as the North−up and the oth-
er one as the Heading−up.This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, an accurate position
may not be shown depending on the
satellite condition, road configuration,
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 using 3 to 4
satellites. The GPS system has a certain
level of inaccuracy built in for security
reasons. While the navigation system will
compensate for this most of the time, oc-
casional positioning errors of up to 300
feet (100 m) can and should be expected.
Generally, position errors will be corrected
within a few seconds.
Limitations of the navigation
system

liii
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 win-
dow tinting contains some metallic
content that will interfere with GPS
signal reception. We advise against
the use of window tinting on vehicles
equipped with navigation systems.
When driving on a small angled Y−
shaped road.
When driving on a spiral road.
When driving on a slippery road such
as in sand, gravel, snow, etc.
When driving on a long straight road.
When freeway and surface streets run
in parallel.
After moving by ferry or vehicle carrier.
When a long route is searched during
high speed driving.
When driving without setting the current
position calibration correctly.
After repeating a change of directions
by going forward and backward, or
turning on a turntable in the parking
lot.
When leaving a covered parking lot or
parking garage.
When a roof carrier is installed.
When driving with the tire chains
installed.
When the tires are worn.
After replacing a tire or tires.
(a) Accurate current vehicle
position may not be shown in
the following cases:
