ROUTE SEARCHING
NOTE:
Except for the ordinance-designated cities and the prefectural capitals (Applicable areas may be changed in the updated map disc.) 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 position 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 position or the passing points may be
intermittent.System is not malfunction.
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 area.)System is not malfunction.
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 position and the destination (passing
points). For this reason, the recommended route
may be detouring.System is not malfunction.
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) Driving condition Remarks (correction, etc.)
Road
configurationY-intersections
At a Y intersection or similar gradual
division of roads, error 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 necessary,
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 stop-
ping, map-matching does not work
effectively enough and distance
errors may accumulate. As a result,
the vehicle mark may deviate from
the correct location when the vehi-
cle turned at a corner.
Zigzag roads
When driving on a zigzag road, the
map may be matched to other roads
in the similar direction nearby at
every turn, and the vehicle mark
may deviate from the correct loca-
tion.
Roads laid out in a grid pattern
When driving at where roads are
laid out in a grid pattern, where
many roads are running in the simi-
lar 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 par-
allel (such as highway and side-
way), the map may be matched to
the other road by mistake and the
vehicle mark may deviate from the
correct location.

PlaceIn a parking lot When driving in a parking lot, or
other location 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
deviated from the correct location.
When driving in circle or turning the
steering wheel repeatedly, direction
errors accumulate, 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 necessary,
direction correction. Turn ta ble
When the ignition switch is OFF, the
navigation system cannot get the
signal from the gyroscope (angular
speed sensor). Therefore, the dis-
played 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 dataRoad 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 devi-
ate 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 vehi-
cle mark may deviate from the cor-
rect road.
Vehicle Use of tire chainsWhen tire chains are used, the mile-
age is not correctly detected, and
the vehicle mark may deviate from
the correct road.Drive the vehicle for a while. If the
distance is still deviated, adjust it
by using the distance adjustment
function. (If the tire chain is
removed, recover the original
value.) Cause (condition) Driving condition Remarks (correction, etc.)

THE CURRENT POSITION 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, 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 being 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.
THE CURRENT POSITION 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
drivingJust after the engine is startedIf the vehicle is driven off just after
the engine is started when the gyro-
scope (angular speed sensor) cor-
rection is not completed, the vehicle
can lose its direction and may have
deviated from the correct location.Wait for a short while before driv-
ing after starting the engine.
Continuous driving without stopping When driving long distances without
stopping, direction errors may accu-
mulate, 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 to
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 necessary,
direction correction.
How to correct
locationPosition 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. 1 mm.
NOTE:
Whenever possible, use detailed
map for the correction.
Direction when location is corrected
If the accuracy of location settings
during correction is poor, accuracy
may be reduced afterwards.Perform direction correction. Cause (condition) Driving condition Remarks (correction, etc.)

NAVIGATION SYSTEM

THE CURRENT LOCATION MARK IS IN A RIVER OR THE SEA
The navigation system moves the current location mark with no distinction between land and rivers or sea. If
the location mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
WHEN DRIVING ON THE SAME ROAD, SOMETIMES THE CURRENT-LOCATION MARK IS IN
THE RIGHT PLACE AND SOMETIMES IT IS THE WRONG PLACE
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, the location detection results will be
different. Therefore, even on a road on which the location has never been wrong, conditions may cause the
vehicle mark to deviate.
LOCATION CORRECTION BY MAP MATCHING IS SLOW

The map matching function needs to refer to the data of the surrounding area. It is necessary to drive
some distance for the function to work.

Because map matching operates on this principle, when there are many roads running in similar direc-
tions in the surrounding area, no matching determination may be made. The location may not be cor-
rected until some special feature is found.
ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT
RETURN TO THE CORRECT LOCATION

The GPS accuracy has an error of about 10 m (30 ft). In some cases the current-location mark may not be
on the correct street, even when GPS location-correction is done.

The navigation system compares the results of GPS location detection with the results from map-match-
ing location detection. The one which is determined to have higher accuracy is used.

GPS location correction may not be performed when the vehicle is stopped.
THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED
The current place name may not be displayed if there are no place names displayed on the map screen.
CONTENTS OF THE DISPLAY DIFFER FOR THE BIRDVIEW® AND THE (FLAT) MAP SCREEN
Difference of the BIRDVIEW
® screen from the flat map screen are as follows.

The current place name displays names which are primarily in the direction of vehicle travel.

The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(flat) map display.

The conditions for display of place names, roads, and other data are different for nearby areas and for
more distant areas.

Some thinning of the character data is done to prevent the display becoming to complex. In some cases
and in some locations, the display contents may differ.

The same place name, street name, etc. may be displayed multiple times.
