Sample tests

–

<To determine if the current-location mark skips at the same position, if so, whether it is caused by map-
matching or by GPS>
Perform test pattern 1.

–

<To determine if the pattern of streets displayed is correct or not>
Perform test pattern 1 & 2.
Compare the track of the vehicle on the map screen and the actual road configuration. For fairly accurate
tracking, plotting shall be made every several hundred meters (feet).

–

<When the distance is adjusted accurately>
Perform test pattern 1 & 2.
Drive on a road of which distance is accurately known (by utilizing distance posts on a highway). Calculate
the rate of change (increased/decreased) of the distance by comparing with the actual distance.

Except for the ordinance-designated cities. (Malfunctioning areas may be changed in the updated map disc.)

Symptom

Cause

Remedy

Voice guide will not operate.

Note: Voice guide is only available at intersections
that satisfy certain conditions (indicated by

●

the map). Therefore, guidance may not be given
even when the route on the map changes direc-
tion.

System is not malfunctioning.

The vehicle is not on the recommended route.

Return to the recommended route or re-
search the route.

Voice guide is turned OFF.

Turn voice guide ON.

Route guide is turned OFF.

Turn route guide ON.

Voice guide does not match the
actual road pattern.

Voice guide may vary with the direction to which
the vehicle is turned and the connection of the
road to other roads.

Drive in conformity to the actual traffic rules.

Symptom

Cause

Remedy

No route is shown.

No road to be searched is found around the des-
tination.

Find wider road (orange road or wider)
nearby and reset the destination and passing
points onto it. Take care of the traveling
direction when there are separate up and
down roads.

Starting point and the destination are too close.

Set the destination at more distant point.

Conditional traffic regulation (day of the week/
time of the day) is set at the area around the cur-
rent location or the destination.

Turn the time-regulating search conditions
OFF. Turn “Avoid regulation time” in the
search conditions OFF.

Indicated route is intermittent.

In some areas, highways (gray routes) are not

used for the search

(Note)

Therefore, the route to

the current location or the passing points may be
intermittent.

System is not malfunctioning.

When the vehicle has passed the
recommended route, it is deleted
from the screen.

A recommended route is controlled by each sec-
tion. When the vehicle has passed the passing
point 1, then the map data from the starting point
up to the passing point 1 will be deleted. (The
data may remain undeleted in some areas.)

System is not malfunctioning.

Detouring route is recommended.

In some areas, highways (gray routes) are not
used for the search. (Note). Therefore, detour
route may be recommended.

Set the route closer to the basic route (gray
route).

A detour route may be shown when some traffic
regulation (one-way traffic, etc.) is set at the area
around the starting point or the destination.

Slightly move the starting point or the desti-
nation, or set the passing point on the route
of your choice.

In the area where highways (gray routes) are
used for the search, left turn has priority around
the current location and the destination (passing
points). For this reason, the recommended route
may be detouring.

System is not malfunctioning.

Landmarks on the map do not
match the actual ones.

This can be happen due to omission or error in
the map data.

As a rule, an updated map DVD-ROM will be
released once a year. Wait until the latest
map has become available.

Recommended route is far from
the starting point, passing points,
and destination.

Starting point, passing points, and destination of
the route guide were set far from the desired
points because route searching data around
these area were not stored.

Reset the destination onto the road nearby. If
this road is one of the highways (gray
routes), an ordinary road nearby may be dis-
played as the recommended route.

EXAMPLES OF CURRENT-LOCATION MARK DISPLACEMENT

Vehicle's travel amount is calculated by reading its travel distance and turning angle. Therefore, if the vehicle
is driven in the following manner, an error will occur in the vehicle's current location display. If correct location
has not been restored after driving the vehicle for a while, perform location correction.

Cause (condition)

–: While driving

ooo: Display

Driving condition

Remarks (correction, etc.)

Road config-
uration

Y–intersections

At a Y intersection or similar gradual divi-
sion of roads, an error in the direction of
travel deduced by the sensor may result in
the current-location mark appearing on the
wrong road.

If after travelling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if nec-
essary, direction correction.

Spiral roads

When driving on a large, continuous spiral
road (such as loop bridge), turning angle
error is accumulated and the vehicle mark
may deviate from the correct location.

Straight roads

When driving on a long, straight road and
slow curve without stopping, map-match-
ing does not work effectively enough and
distance errors may accumulate. As a
result, the vehicle mark may deviate from
the correct location when the vehicle is
turned at a corner.

Zigzag roads

When driving on a zigzag road, the map
may be matched to other roads in the simi-
lar direction nearby at every turn, and the
vehicle mark may deviate from the correct
location.

Roads laid out in a grid pattern

When driving where roads are laid out in a
grid pattern, or where many roads are run-
ning in the similar direction nearby, the
map may be matched to them by mistake
and the vehicle mark may deviate from the
correct location.

Parallel roads

When two roads are running in parallel
(such as highway and sideway), the map
may be matched to the other road by mis-
take and the vehicle mark may deviate
from the correct location.

Place

In a parking lot

When driving in a parking lot, or other loca-
tion where there are no roads on the map,
matching may place the vehicle mark on a
nearby road. When the vehicle returns to
the road, the vehicle mark may have devi-
ated from the correct location.
When driving in circle or turning the steer-
ing wheel repeatedly, direction errors accu-
mulate, and the vehicle mark may deviate
from the correct location.

If after travelling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if nec-
essary, direction correction.

Turntable

When the ignition switch is OFF, the navi-
gation system cannot get the signal from
the gyroscope (angular speed sensor).
Therefore, the displayed direction may be
wrong and the correct road may not be
easily returned to after rotating the vehicle
on a turntable with the ignition OFF.

Slippery roads

On snow, wet roads, gravel, or other roads
where tires may slip easily, accumulated
mileage errors may cause the vehicle mark
to deviate from the correct road.

Slopes

When parking in sloped garages, when
travelling on banked roads, or in other
cases where the vehicle turns when tilted,
an error in the turning angle will occur, and
the vehicle mark may deviate from the
road.

Map data

Road not displayed on the map screen

When driving on new roads or other roads
not displayed on the map screen, map
matching does not function correctly and
matches the location to a nearby road.
When the vehicle returns to a road which is
on the map, the vehicle mark may deviate
from the correct road.

Different road pattern
(Changed due to repair)

If the road pattern stored in the map data
and the actual road pattern are different,
map matching does not function correctly
and matches the location to a nearby road.
The vehicle mark may deviate from the
correct road.

Vehicle

Use of tire chains

When tire chains are used, the mileage is
not correctly detected, and the vehicle
mark may deviate from the correct road.

Drive the vehicle for a while. If
the distance still deviates,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.)

CURRENT-LOCATION MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG

In the following cases, the current-location mark may appear on completely different position in the map
depending on the GPS satellite signal receiving conditions. In this case, perform location correction and direc-
tion correction.

●

When location correction has not been done

–

If the receiving conditions of the GPS satellite signal is poor, or if the current-location mark becomes out of
place, it may move to a completely different location and not come back if location correction is not done.
The position will be corrected if the GPS signal can be received.

●

When the vehicle has traveled by ferry, or when the vehicle has been towed

–

Because calculation of the current location cannot be done when travelling with the ignition OFF, for
example when traveling by ferry or when being towed, the location before travel is displayed. If the precise
location can be detected with GPS, the location will be corrected.

CURRENT-LOCATION MARK JUMPS

In the following cases, the current-location mark may appear to jump as a result of automatic correction of the
current location.

●

When map-matching has been done

–

If the current location and the current-location mark are different when map-matching is done, the current-
location mark may seem to jump. At this time, the location may be “corrected” to the wrong road or to a
location which is not on a road.

●

When GPS location correction has been done

–

If the current location and the current-location mark are different when the location is corrected using GPS
measurements, the current-location mark may seem to jump. At this time, the location may be “corrected”
to a location which is not on a road.

Precautions
for driving

Just after the engine is started

If the vehicle is driven just after the engine
is started when the gyroscope (angular
speed sensor) correction is not completed,
the vehicle can lose its direction and may
have deviated from the correct location.

Wait for a short while before
driving after starting the engine.

Continuous driving without stopping

When driving long distances without stop-
ping, direction errors may accumulate, and
the current-location mark may deviate from
the correct road.

Stop and adjust the orientation.

Abusive driving

Spinning the wheels or engaging in other
kinds of abusive driving may result in the
system being unable perform correct
detection, and may cause the vehicle mark
to deviate from the correct road.

If after travelling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if nec-
essary, direction correction.

How to cor-
rect location

Position correction accuracy

If the accuracy of location settings is poor,
accuracy may be reduced when the correct
road cannot be found, particularly in places
where there are many roads.

Enter in the road displayed on
the screen with an accuracy of
approx. 1mm.
Caution: Whenever possible,
use detailed map for the cor-
rection.

Direction when location is corrected

If the accuracy of location settings during
correction is poor, accuracy may be
reduced afterwards.

Perform direction correction.
