Vehicle location accuracy is low. Accuracy indicator (GPS satellite mark) on the
map screen stays gray.Current location is not determined.
Vehicle speed setting by the vehicle speed pulse
has been deviated (advanced or retarded) from
the actual vehicle speed because tire chain is fit-
ted or the system has been used on another vehi-
cle.Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19 MPH)] and
the deviation will be automatically adjusted. If
advancement or retard still occur, perform
the distance adjustment by CONFIRMA-
TION/ADJUSTMENT mode of diagnosis
function.
Map data has error or omission. (Vehicle mark is
always deviated to the same position.)As a rule, an updated map DVD–ROM will be
released once a year. 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 route guide ON.
Route information is not available on the dark
green route.System is not malfunctioning.
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 rec-
ommended 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). Howev-
er, the result is the same as that of
the previous search.Performed search with every condition consid-
ered. However, the result is the same as that of the
previous search.System is not malfunctioning.
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 sharing in
several steps.
When setting the route, the starting
point cannot be selected.The current vehicle location is always set as the
starting point of a route.System is not malfunctioning.
Some menu items cannot be se-
lected.The vehicle is being driven. Stop the vehicle at a safe place and then op-
erate the system.

ROUTE SEARCH
NOTE:
Except for the ordinance-designated cities. (Malfunctioning areas may be changed in the updated map disc.)
EXAMPLES OF CURRENT-LOCATION MARK DISPLACEMENT
Symptom Cause Remedy
Voice guide will not operate. Note: Voice guide is only available at intersections
that satisfy certain conditions (indicated by l on the
map). Therefore, guidance may not be given even
when the route on the map changes direction.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 ac-
tual 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) near-
by and reset the destination and passing
points onto it. Take care of the traveling direc-
tion 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 destina-
tion, 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 displayed as
the recommended route.

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 exam-
ple when traveling by ferry or when being towed, the location before travel is displayed. If the precise loca-
tion 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 loca-
tion 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.
CURRENT-LOCATION MARK IS IN A RIVER OR 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 SAME ROAD, SOMETIMES CURRENT-LOCATION MARK IS IN RIGHT
Precautions
for drivingJust after the engine is startedIf 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 detec-
tion, and may cause the vehicle mark to de-
viate from the correct road.If after travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.
How to cor-
rect 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. 1mm.
Caution: Whenever possible,
use detailed map for the correc-
tion.
Direction when location is corrected
If the accuracy of location settings during
correction is poor, accuracy may be re-
duced afterwards.Perform direction correction. Cause (condition) –: While driving ooo: Display Driving condition Remarks (correction, etc.)
