If you wish to look at a different point on
the map other than your current vehicle
position, you can bring the desired point
to the center of the screen by using the
scroll feature.
Move the cursor mark
to the point you
desire by operating the select and scroll
lever of the navigation controller. Push the
“ENT” button on the navigation control-
ler, and select the
“Enter ” switch.
If you continue to hold the lever by your
finger on the navigation controller, the
map will continue scrolling in that direction
until you lift your finger. After scrolling the screen, the map re-
mains centered at the selected location
until you push the
“MAP/VOICE” but-
ton. The current vehicle position mark will
continue to move along your actual route
and may move off the screen. When you
push the
“MAP/VOICE” button, the
current vehicle position mark returns to
the center of the screen and the map
moves as you proceed on your route.
INFORMATION
If you enter a destination using the
screen scrolling function, the road
nearest to the point you selected is
set as the destination. At this time, if
the nearest road is over 4 miles from
destination point, the system may not
be able to calculate a guidance route.
You can change the orientation of the
map from “Northup” to “Headingup”.

3. When there are 2 map screens dis-played to switch the “North
up”/“Headingup” of the right screen
map, select
“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
other 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 up to 300 feet
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 installation of window tinting may also
obstruct the GPS signals. Most window
tinting contains some metallic content that
will interfere with the GPS signal recep-
tion. We recommend not to use the win-
dow tinting on vehicles equipped with nav-
igation systems.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.
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:

AVALON_Navi_U (L/O 0205)
512003 AVALON NAVI (OM41403U)
When using tires that are smaller or
larger than the factory specifications.
When the tire pressure in any of the
four tires is not correct.
INFORMATION
If your vehicle cannot receive GPS
signals, you can correct the current
position manually. For the information
on setting the current position cal-
ibration, see page 78.
When turning at a wrong intersection
off the designated route guidance.
If you are heading for a destination
without passing through a set preferred
road, automatic rerouting may display
a route returning to the set preferred
road.
When turning at an intersection, there
is no route guidance.
When passing through the intersection,
there is no route guidance.
During automatic rerouting, the route
guidance may not be available for the
next turn to the right or left.
It may take a long time to operate
automatic rerouting during high speed
driving. In automatic rerouting, a detour
route may be shown.
During automatic rerouting, the route
may not be changed.
The route in a U−turn may be shown
or announced.
A location may have multiple names
and the system will announce one or
more.
Some routes may not be searched.
If the route to your destination includes
gravel, unpaved roads or alleys, the
route guidance may not be shown.
Your destination point might be shown
on the opposite side of the street.
When a portion of the route has regu-
lations prohibiting the entry of the ve-
hicle that vary by time or season or
other reason.
The road and map data stored in your
navigation system may not be complete
or may not be the latest release.
After replacing the tire, implement the
operation described in the “Current
position calibration”. (For details, see
page 78.)
This navigation system uses the tire turn-
ing data and is designed to work with
factory −specified tires for your Toyota.
Installing tires that are larger or smaller
than the originally equipped diameter may
cause inaccurate display of the vehicle’s
position. The tire pressure also affects the
diameter of the tires so please make sure
the tire pressure of all four tires is cor-
rect.
(b) Inappropriate route
guidance may occur in the
following cases:

for route guidance. (See the following
pages.) In one type of area, primarily
around metropolitan centers, detailed
route guidance is available for the en-
tire area. In the other type of area, all
roads are displayed on the map but
route guidance is limited. The naviga-
tion route might lack precision because
the data (no right turns, oneway traf-
fic, etc.) is not completed. It is still
possible to reach the destination by fol-
lowing the arrow direction and distance
as shown on the bottom left of the
screen. The arrow points in the direc-
tion of the destination. The distance
shown is as measured in a straight line
from the current vehicle position to the
destination area.
In order to provide you with accurate map
information as much as possible, we are
always gathering information such as road
repairs and doing site investigation. How-
ever, the names of roads, streets, facili-
ties, and their locations are often
changed. In some places, construction on
roads may be in progress. For that rea-
son, information on some areas in this
system might be different from the actual
location.
