DIAGNOSIS SYSTEM
SPEAKER TEST
When selecting “Speaker Test”, speaker diagnosis screen is dis-
played. When pressing “Start”, test tone sounds from the speaker. At
that time, when pressing “Start”, test tone sounds from next speaker.
Then, when pressing the “Stop”, test tone stops.
NOTE:
The frequency of test tone emitted from each speaker is as follows.
NAVIGATION
Steering Angle Adjustment
The steering angle output value detected with the gyroscope can be
adjusted.
Speed Calibration
Usually the automatic distance correction function adjusts the mal-
function in distance caused by the tires wearing down or the tire
pressure change. If prompt adjustment is necessary when the tire
chains are installed etc., perform this.Tw e e t e r : 3 k H z
Front door speaker : 300 Hz

VOICE GUIDANCE
VOICE RECOGNITION
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. Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The voice guidance is not avail-
able.Voice guidance is only available at certain intersec-
tions. In some cases, voice guidance is not avail-
able even when the vehicle should make a turn.This is not a malfunction.
The vehicle has deviated from the suggested
route.Go back to the suggested route or request
route calculation again.
Voice guidance is set to off. Turn on the voice guidance.
Route guidance is set to off. Turn on the voice guidance.
The guidance content does not
correspond to the actual condition.The content of the voice guidance may vary,
depending on the types of intersections at which
turns are made.Follow all traffic rules and regulations.
Symptom Possible cause Possible solution
The system does not recognize
the command.
The system recognizes the com-
mand incorrectly.The interior of the vehicle is too noisy.Close the windows or have other occu-
pants be quiet.
The volume of the voice is too low. Speak louder.
Pronounceation is unclear. Speak clearly.
Voice recognition mode is not yet ready to speak.Push the release “PPT” on the steering
switch, and speak a command after the
tone sounds.
5 seconds or more have passed after pushed and
released “PTT” on the steering switch.Make sure to speak a command within 5
seconds after push and release “PTT” on
the steering switch.
Only a limited range of voice commands is usable
for each screen.Use a correct voice command appropriate
for the current screen.

TROUBLE DIAGNOSIS
PlaceIn a parking lotWhen 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 loca-
tion.
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 traveling about 10 km (6
MPH) the correct location has not
been restored, perform location
correction and, if necessary, direc-
tion correction. TurntableWhentheignitionswitchisOFF,the
navigation system cannot receive
the signal from the gyroscope
(angular speed sensor). Therefore,
the displayed direction may be
incorrect and the correct road may
not be easily returned to after rotat-
ing the vehicle on a turntable with
the ignition 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 traveling 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 dataRoads not displayed on the map
screenWhen 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. Cause (condition) Driving condition Remarks (correction, etc.)

TROUBLE DIAGNOSIS
–Because calculation of the current location cannot be done when traveling 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-
tioncanbedetectedwithGPS,thelocationwillbecorrected.
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.
lWhen map matching has been done
–If 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 incorrect road or to a
location which is not on a road.
lWhen GPS location correction has been done
–If current location and the current location mark are different when location is corrected using GPS mea-
surements, 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.
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.
CURRENT LOCATION MARK ROTATES WITHOUT OPERATION
If the ignition switch is turned ON with the turntable rotating, the rotating condition is recorded as the stop con-
dition. Therefore, the current location mark might rotate when actually stopping.
WHEN DRIVING ON THE SAME ROAD, SOMETIMES THE CURRENT LOCATION MARK IS IN
THE CORRECT PLACE AND SOMETIMES IT IS IN THE INCORRECT PLACE.
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and operation of the steering wheel, the location detection results will be dif-
ferent. Therefore, even on a road on which the location has never been incorrect, conditions may cause the
vehicle mark to deviate.
LOCATION CORRECTION BY MAP MATCHING IS SLOW.
lThe 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.
lBecause of the way map matching operates, when there are many roads running in similar directions in
the surrounding area a matching determination may be impossible. The location will remain uncorrected
until some special feature is found.
ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT
RETURN TO THE CORRECT LOCATION.
lGPS accuracy has a malfunction range of about 10 m. In some cases the current location mark may not
be on the correct street, even when GPS location correction is done.
lThe navigation system compares the results of GPS location detection with the results from map-match-
ing location detection. The one that is determined to have higher accuracy is used.
lPosition correction by GPS is not available while the vehicle is stopped.
THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED.
The current place name might not be displayed when there is no name of place information in the map screen.
THE DISPLAY IS DIFFERENT BETWEEN BIRDVIEW®AND (FLAT) MAP DISPLAY.
The following is different at birdview®.
lThe current place name displays names that are primarily in the direction of vehicle travel.
lThe amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(flat) map display.
lThe conditions for display of place names, roads, and other data are different for nearby areas and for
more distant areas.
lSome trimming of the character data is done to prevent the display from becoming too complex. In some
cases and in some locations, the display contents may differ.
lThe same place name, street name, etc. may be displayed multiple times.
