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.

−
shaped road.

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:

Distance
The distance calibration function is to
be used when the tires are replaced.
This will adjust for any possible change
in tire circumference from the old tires
to the new ones. If this procedure 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. 1. Push the
“MENU” button to dis-
play the “Menu” screen.
