DRIVING TEST=NBEL0234S03During the driving test, diagnose the system by checking the dif-
ference of symptoms with each sensor ON or OFF.
Test pattern 1
Test method in which current position adjustment is not made
according to GPS data.
IRemove the GPS antenna connector from the display & NAVI
control unit. Drive the vehicle.
Before driving the vehicle, perform ªADJUST CURRENT
LOCATIONº (EL-411).
Test pattern 2
Test procedure in which map matching is not used.
IBefore driving the vehicle, perform ªADJUST CURRENT
LOCATIONº (EL-411). With the ignition switch OFF and the
map CD-ROM removed from the display & NAVI control unit,
drive the vehicle. After driving the vehicle, reinstall the map
CD-ROM. Compare the saved driving tracks for the vehicle's
current location with roads on the map.
Example
when driving in the same area. Determine if this is the result of the
map matching function or the GPS function.>
,Perform test pattern 1.
display>
,Perform test patterns 1 and 2.
ICompare the map and the saved driving tracks. The precision
of the saved driving tracks is within several hundred meters.

,Perform test patterns 1 and 2.
IMake adjustments by driving the vehicle over a known course
(highway or other road where distances are clearly marked).
Calibrate the distance against the known distance. Use the
formula below.
Calibration value = Screen display distance/Actual distance

Trouble diagnoses (Cont'd)
EL-419

GPS signal reception conditions are good. However, the position mark does not return to its proper
position.
Ihe system senses the vehicle location with an error of approximately 100 m (328 ft). Due to the limitation
of precision, the position marker may be inaccurate even if the GPS signal reception condition is good.
IThe navigation system uses GPS data to determine vehicle location. GPS data is compared with other
locational sensing data during the map matching process. The system decides which data is more pre-
cise and uses that data.
IWhen the vehicle is stationary, GPS data cannot be used to make system corrections.
Area designations on the map display and the BIRDVIEWTdisplay differ.
To prevent the display from becoming congested, alphanumeric information is abridged.
[No problem]
Correct position of your vehicle is not displayed.
Vehicle position changed after ignition key was turned to the OFF position (Vehicle is transported on car ferry,
car train, or by some other means).
[Operate vehicle for short time under GPS receiving conditions.]
The display does not change to night-time mode even though the light switch has been turned ON.
Lights have been turned on. In ªDISPLAY CHANGEº mode, night-time mode on display has been switched to
day-time mode and still is.
[Turn lights on again. Set the display to night-time mode. Refer to EL-412.]
Map does not scroll even though the position of your vehicle is changed.
Present area does not appear on the display.
[Press the ªMAPº switch.]
Vehicle position marker does not appear.
Present area does not appear on the display.
[Press the ªMAPº switch.]
The map surface precision display (GPS satellite marker) still remains gray.
Vehicle is parked inside a building or in the shadow of a large building. This intercepts the GPS signal.
[Move the vehicle to a more open position.]
GPS signal is not received because objects are placed on the rear parcel shelf.
[Remove objects from the rear parcel shelf.]
GPS satellite position is bad.
[Wait until GPS satellite position improves.]
Vehicle position precision is bad.
The map surface precision display (GPS satellite marker) still remains gray.
[Refer to ªThe map surface precision display (GPS satellite marker) still remains grayº item (Symptoms)]
Vehicle speed and elapsed distance is calculated from the vehicle speed pulse. This pulse is dependent upon
tire size. If tire chains are used on the vehicle, accuracy will be affected (pulse rate will be too fast or too slow).
The same is true if the system installed to your vehicle is removed and installed on another vehicle.
[Drive the vehicle at a speed higher than 30 km/h (19 MPH) for approximately 30 minutes. Automatic read-
justment should occur. If it does not (remains too fast or too slow), distance calibration is required. Or, drive
the vehicle for a short distance. Perform ªSPEED CALIBRATIONº (EL-409). After removing the tire chains,
sensing accuracy may recover by itself.]
Bad map data or system defect (same error consistently occurs in the same area)
ROUTE SEARCH/ROUTE GUIDENBEL0235S03IIf the present location or the destination location is displayed in the avoid area, it is not possible to search
routes.
IIf the avoid area is set to wide range area, it may not be possible to find appropriate routes or search for
alternate routes.
IThe automatic re-route calculates a return to the original route. Because of this, it may not be possible to
search appropriate new routes. If you deviate from the original route and wish to select an appropriate new
route, touch ªRoute Calculationº.
IThe automatic re-route function may sometimes require considerable time.
IDisplayed route number and directional information at a highway junction may differ from the information
posted on the actual road signs.
IDisplayed street name information at a highway exit may differ from the information posted on the actual
road signs.
IStreet name information displayed on the enlarged intersection map may differ from the information posted
on the actual road signs.

DISPLAY SCREENNBHA0016S01Displays the operational status of the system.
AUTO SWITCHNBHA0016S02The compressor, intake doors, air mix door, outlet doors, and blower speed are automatically controlled so
that the in-vehicle temperature will reach, and be maintained at the set temperature selected by the operator.
ECON SWITCHNBHA0016S03By pressing the ECON switch, the display should indicate ECON and the compressor always turns OFF. With
the compressor OFF, the system will not remove heat (cool) or de-humidify. The system will maintain the in-
vehicle temperature at the set temperature when the set temperature is above the ambient (outside) tempera-
ture. The system will set the intake doors to the outside air position.

NBHA0016S04Increases or decreases the set temperature.
OFF SWITCHNBHA0016S05The compressor and blower are OFF, the intake doors are set to the outside air position, and the air outlet
doors are set to the foot (80% foot and 20% defrost) position.
FAN SWITCHNBHA0016S06Manually controls the blower speed. Four speeds are available for manual control (as shown on the display
screen):
