DESTINATION, PASSING POINTS, AND MENU ITEMS CANNOT BE SELECTED/SETNJEL0633S03
Symptom Cause Remedy
Destination cannot be set. Destination to be set is on an expressway. Set the destination on an ordinary road.
Passing point is not searched
when re-searching the route.The vehicle has already passed the passing
point, or the system judged so.To include the passing points that have
been passed into the route again, set the
route again.
Route information will not be dis-
played.Route searching has not been done. Set the destination and perform route
searching.
Vehicle mark is not on the recommended route. Drive on the recommended route.
Route guide is turned OFF. Turn the route guide ON.
Route information is not available on the dark
pink route.System is not malfunction.
After the route searching, no
guide sign will appear as the
vehicle goes near the entrance/
exit to the toll road.Vehicle mark is not on the recommended route.
(On the display, only guide signs related to the
recommended route will be shown.)Drive on the recommended route.
Automatic route searching is not
possible.Vehicle is driving on a highway (gray route), or
no recommended route is available.Drive on a road to be searched. Or
re-search the route manually. In this case,
however, the whole route will be searched.
Performed automatic detour
search (or detour search).
However, the result is the same
as that of the previous search.Performed search with every conditions consid-
ered. However, the result is the same as that of
the previous search.System is not malfunction.
Passing points cannot be set. More than five passing points were set. Passing points can be set up to five. To
stop at more than five points, perform shar-
ing in several steps.
When setting the route, the start-
ing point cannot be selected.The current vehicle location is always set as the
starting point of a route.System is not malfunction.
Some menu items cannot be
selected.The vehicle is being driven. Stop the vehicle at a safe place and then
operate the system.
VOICE GUIDENJEL0633S04
Symptom Cause Remedy
Voice guide will not operate. Note: Voice guide is only available at intersec-
tions that satisfy certain conditions (indicated by
on the map). Therefore, guidance may not be
given even when the route on the map changes
direction.System is not malfunction.
The vehicle is not on the recommended route. Return to the recommended routeorre-
search the route.
Voice guide is turned OFF. Turn the voice guide ON.
Route guide is turned OFF. Turn the route guide ON.
Voice guide does not match the
actual road pattern.Voice guide may vary with the direction to which
the vehicle is turn and the connection of the road
to other roads.Drive in conformity to the actual traffic
rules.

ROUTE SEARCHINGNJEL0633S05
Symptom Cause Remedy
No route is shown. No road to be searched is found around the
destination.Find wider road (orange road or wider)
nearby and reset the destination and pass-
ing 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
current 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 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
section. When the vehicle has passed the pass-
ing 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) arenot
used for the search. 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 destina-
tion.Slightly move the starting point or the
destination, 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 (pass-
ing 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 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 lat-
est 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
displayed as the recommended route.

EXAMPLES OF CURRENT-LOCATION MARK DISPLACEMENT=NJEL0633S06Vehicle’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.

Road con-
figurationY-intersections
ELK0192D
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
ELK0193D
When driving on a large, continuous
spiral road (such as loop bridge), turn-
ing angle error is accumulated and the
vehicle mark may deviate from the
correct location.
Straight roads
ELK0194D
When driving on a long, straight road
and slow curve without stopping, map-
matching does not work effectively
enough and distance errors may accu-
mulate. As a result, the vehicle mark
may deviate from the correct location
when the vehicle turned at a corner.
Zigzag roads
ELK0195D
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 location.
Roads laid out in a grid pattern
ELK0196D
When driving at where roads are laid
out in a grid pattern, where many
roads are running in the similar direc-
tion nearby, the map may be matched
to them by mistake and the vehicle
mark may deviate from the correct
location.
Parallel roads
ELK0197D
When two roads are running in parallel
(such as highway and sideway), 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
SEL709V
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 table
SEL710V
When the ignition switch is OFF, the
navigation system cannot get the sig-
nal from the gyroscope (angular speed
sensor). Therefore, the displayed
direction may be wrong and the cor-
rect road may not be easily returned to
after rotating the vehicle on a turn
table with the ignition switch OFF.
Slippery roadsOn 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.
SlopesWhen 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
SEL699V
When driving on new roads or other
roads not displayed on the map
screen, map matching does not func-
tion 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)
ELK0201D
If the road pattern stored in the map
data and the actual road pattern are
different, map matching does not func-
tion correctly and matches the location
to a nearby road. The vehicle mark
may deviate from the correct 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.)

Precautions
for drivingJust after the engine is startedIf the vehicle is driven off 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 driv-
ing after starting the engine.
Continuous driving without stoppingWhen driving long distances without
stopping, direction errors may
accumulate, and the current-location
mark may deviate from the correct
road.Stop and adjust the orientation.
Abusive drivingSpinning 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 cor-
rect locationPosition correction accuracy
SEL699V
If the accuracy of location settings is
poor, accuracy may be reduced when
the correct road cannot be found, par-
ticularly 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
SEL702V
If the accuracy of location settings dur-
ing correction is poor, accuracy may
be reduced afterwards.Perform direction correction.
THE CURRENT POSITION MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG.NJEL0633S07In 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
direction 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 pre-
cise location can be detected with GPS, the location will be corrected.
THE CURRENT POSITION MARK JUMPS.NJEL0633S08In 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 whenmap 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 whenthe 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.
THE CURRENT LOCATION MARK IS IN A RIVER OR THE SEA.NJEL0633S09The navigation system moves the current location mark with no distinctionbetween 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.
NJEL0633S10The 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, thelocation 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.NJEL0633S11The 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 roadsrunning in similar direc-
tions in the surrounding area, no matching determination may be made. The location may not be corrected
until some special feature is found.
ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT
RETURN TO THE CORRECT LOCATION.
NJEL0633S12The 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 withthe results from map-match-
ing location detection. The one which is determined to have higher accuracyisused.
GPS location correction may not be performed when the vehicle is stopped.
THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED.NJEL0633S13The 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.
NJEL0633S14Difference of the BIRDVIEW Screen From the Flat Map Screen Are as Follows.NJEL0633S1401The current place name displays names which are primarily in the directionof 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 becomingto 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.
