The movement is slow.

The temperature in the interior of the vehicle is
low.

Wait until the interior of the vehicle has warmed
up.

Some pixels in the display are
darker or brighter than others.

This condition is an inherent characteristic of liq-
uid crystal displays.

the navigation system.

Symptom

Possible cause

Possible solution

Symptom

Possible cause

Possible solution

Names of roads and locations dif-
fer between plan view and BIRD-

VIEW

™

.

This is because the quantity of the displayed in-
formation is reduced so that the screen does not
become difficult to read. There is also a chance
that names of the roads or locations may be dis-
played several times, and the names appearing
on the screen may be different because of a pro-
cessing procedure.

This is not a malfunction.

The vehicle mark is not displayed
in the correct position.

The vehicle was transported after the ignition
switch was turned off, for example, by a ferry or
car transporter.

Drive the vehicle for a while on a road where
GPS signals can be received.

The position and direction of the vehicle mark
may be incorrect depending on the driving envi-
ronments and the levels of positioning accuracy
of the navigation system.

This is not a malfunction. Drive the vehicle for a
while to automatically correct the position and
direction of the vehicle mark.

When the vehicle is travelling on a
new road, the vehicle mark is lo-
cated on another road nearby.

The system automatically places the vehicle
mark on the nearest available road, because the
new road is not stored in the map data.

Updated road information will be included in the
next version of the DVD-ROM.

The screen does not switch to the
night screen even after turning on
the headlights.

The daytime screen was set the last time the
headlights were turned on.

Set the screen to the night screen mode using

button when turning on the headlights.

The map does not scroll even
when the vehicle is moving.

The current location map screen is not dis-
played.

Press the “MAP” button.

The vehicle mark is not displayed.

The current location map screen is not dis-
played.

Press the “MAP” button.

The GPS indicator on the screen
remains gray.

GPS signals cannot be received depending on
the vehicle location, such as in a parking ga-
rage, on a road that has numerous tall buildings,
etc.

Drive on an open, straight road for a while.

A sufficient amount of GPS satellites is not avail-
able.

Please wait for the satellites to move to loca-
tions available for the navigation system.

The location of the vehicle mark is
misaligned from the actual posi-
tion.

When using tire chains or replacing the tires,
speed calculations based on the speed sensor
may be incorrect.

Drive the vehicle for a while [at approximately
30 km/h (19 MPH) for about 30 minutes] to au-
tomatically correct the vehicle's mark position.
If this does not correct the vehicle mark posi-
tion, inspect the AV system.

The map data has a mistake or is incomplete
(the vehicle mark position is always misaligned
in the same area).

Updated road information will be included in the
next version of the DVD-ROM.

Symptom

Possible cause

Possible solution

In the auto re-route calculation,
waypoints are not included.

Waypoints that you have already passed are not
included in the auto re-route calculation.

To go to that waypoint again, it is necessary to
edit the route.

Route information is not displayed.

Route calculation has not yet been performed.

Set the destination and perform route calcula-
tion.

Vehicle is not driving on the suggested route.

Drive on the suggested route.

Route guidance is set to off.

Turn on the route guidance.

The auto re-route calculation (or
detour calculation) suggests the
same route as the one previously
suggested.

Route calculations took priority conditions into
consideration, but the same route was calculat-
ed.

This is not a malfunction.

A waypoint cannot be added.

Five waypoints are already set on the route, in-
cluding the ones that you have already passed.

A maximum of 5 waypoints can be set on the
route. If you want to go to 6 or more waypoints,
perform route calculations several times, as
necessary.

The suggested route is not dis-
played.

Roads near the destination cannot be calculat-
ed.

Reset the destination to a main or ordinary
road, and recalculate the route.

The starting point and destination are too close.

Set a more distant destination.

The starting point and destination are too far
away.

Divide your trip by selecting one or two interme-
diate destinations, and perform a global route
calculation based on multiple route calcula-
tions.

There are time restricted roads (day of week,
time) near the current vehicle location or desti-
nation.

Set [Use Time Restricted Roads] to off.

The part of the route already
passed is deleted.

A route is managed by sections between way-
points. If passing the first waypoint, the section
between the starting point and the waypoint is
deleted. (It may not be deleted depending on the
area.)

This is not a malfunction.

An indirect route is suggested.

If there are restrictions (such as one-way
streets) on roads close to the starting point or
destination, the system may suggest an indirect
route.

Adjust the location of the starting point or desti-
nation.

The system may suggest an indirect route be-
cause route calculation does not take into con-
sideration some areas such as narrow streets
(grey roads).

Reset the destination to a main or ordinary
road, and recalculate the route.

The landmark information does not
correspond to the actual informa-
tion.

This may be caused by insufficient or incorrect
data on the DVD-ROM.

Updated information will be included in the next
version of the DVD-ROM.

The suggested route does not ex-
actly connect with the starting
point, waypoints, or destination.

There is no data for route calculation closer to
these locations.

Set the starting point, waypoints and destina-
tion on a main road, and perform route calcula-
tion.
