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.

INFORMATION
If your vehicle cannot receive GPS
signals, you can correct the current

on setting the current position cal-
ibration, see page 80.
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

When passing through an intersection
for which there is no route guidance.
During automatic rerouting, the route
guidance may not be available for the

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 reasons.
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 80.)
This navigation system uses tire turning
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 posi-
tion. 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:

POSITION/DIRECTION CALIBRATION
1. Move the cursor mark to your
desired point by operating the select
and scroll lever of the navigation
controller.
Push the
“ENTER” button on the navi-
gation controller.
2. Operate the select and scroll lever of
the navigation controller, so that the
screen direction is facing to your
desired direction.
Push the
“ENTER” button on the navi-
gation controller, and then the map screen
will be displayed. TIRE CHANGE CALIBRATION
The tire change calibration function
should be used when the tires are re-
placed. This will adjust for any possible
change in tire circumference from the
old tires to the new ones. If this proce-
dure is not performed when tires are
replaced, the current vehicle position
mark may become incorrect.
To execute the fast distance tire calibra-
tion procedure, select the
“Tire
change”
switch on the “Calibration”
screen.
The message appears and the fast dis-
tance calibration is automatically started.
A few seconds later, the map screen will
be displayed.
