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.

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 61.
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 61.)
This navigation system uses the tire turn-
ing data and is designed to work with
factory−specified tires for your vehicle.
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:

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.
The map database is normally updated
once a year. Contact your dealer for up-
dating a map database.
INFORMATION
For the up dated map DVD ROM, con-
tact your Toyota dealer.
