No voice guidance is available.
The volume is too high or too low.

The volume is not set correctly, or it is turned off.

Adjust the volume of voice guidance.

Volume guidance is not provided for narrow streets
(roads displayed in gray).

This is not a malfunction.

No map is displayed on the screen.

The map DVD-ROM is not inserted, or it is inserted
upside down.

Insert the map DVD-ROM correctly.

The screen is too dim.
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.

crystal displays.

This is not a malfunction.

Some menu items cannot be
selected.

Some menu items become unavailable while the
vehicle is driven.

Park the vehicle in a safe location, and
then operate the navigation system.

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 infor-
mation is reduced so that the screen does not
become too crowded. There is also a chance that
names of the roads or locations may be displayed
multiple times, and the names appearing on the
screen may be different because of a processing
procedure.

This is not a malfunction.

The vehicle icon 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 trans-
porter.

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

The position and direction of the vehicle may be
incorrect depending on the driving environments and
the levels of positioning accuracy of the navigation
system.

This is not a malfunction. Drive the vehi-
cle for a while to automatically correct the
position and direction of the vehicle icon.

When the vehicle is travelling on a
new road, the vehicle icon is
located on another road nearby.

Because the new road is not stored in the map data,
the system automatically places the vehicle ion on
the nearest road available.

Updated road information will be included
in the next version of the map 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 head-
lights were turned on.

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

ROUTE CALCULATION AND VISUAL GUIDANCE

The GPS indicator on the screen
remains gray.

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

Drive on an open, straight road for a
while.

GPS signals cannot be received because objects
are placed on the instrument panel.

Remove the objects from the instrument
panel.

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

Wait for the satellites to move locations
available for navigation system.

The location of vehicle icon is mis-
aligned from the actual position.

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 approxi-
mately 30 km/h (19 MPH) for about 30
minutes] to automatically correct the vehi-
cle icon position.
If this does not correct the vehicle icon
position, inspect AV system.

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

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

REAR VIEW MONITOR

The part of the route already
passed is deleted.

A route is managed by sections between way-
points. If you passed 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
destination.

The system may suggest an indirect route because
route calculation does not take into consideration
some areas such as narrow streets (gray 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 caused by insufficient or incorrect data on
the DVD-ROM.

This is not a malfunction.

The suggested route does not
exactly connect to the starting
point, waypoints, or destination.

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

Set the starting point, waypoints and desti-
nation on main road, and perform route cal-
culation.
