Error historyDiagnosis results previously stored in the memory
(before turning ignition switch ON) are displayed in this
mode. Time and location when/where the errors
occurred are also displayed.EL-479
Longitude & LatitudeDisplay the map. Use the joystick to adjust position. Lon-
gitude and latitude will be displayed.EL-486
Adjust the AngleTurning angle of the vehicle on the display can be
adjusted in this mode.EL-487
Speed CalibrationUnder ordinary conditions, the navigation system dis-
tance measuring function will automatically compensate
for minute decreases in wheel and tire diameter caused
by tire wear or low pressure. Speed calibration immedi-
ately restores system accuracy in cases such as when
distance calibration is needed because of the use of tire
chains in inclement weather.EL-488
Initialize LocationThis mode is for initializing the current location. Use
when the vehicle is transported a long distance by a
trailer, etc.EL-489

HOW TO PERFORM SELF-DIAGNOSIS MODENJEL0519S021. Start the engine.
2. Push ªOPEN/CLOSEº switch and then open the display.
3. Push both of ªMAPº and ªMODEº switches at the same time for
more than five seconds.
SEL527X
4. Select ªSelf Diagnosisº or ªConfirmation/ adjustmentº.
+For further procedure, refer to the following pages which
describe each application item of the self-diagnosis mode.

ªINITIALIZE LOCATIONº MODE=NJEL0520S09This procedure is for initializing the current location. Perform ªIni-
tialize Locationº when the vehicle has been transported a long dis-
tance by trailer, etc.
Map with grey background appears and the vehicle location can-
not be adjusted by scrolling the display when the vehicle location
in the memory is out of the area of the inserted map data.
Perform ªInitialize Locationº when this occurs.
NOTE:
+Only initialize the system when the NAVI control unit is
replaced. If the system is initialized in other cases, it may
cause inaccurate positioning of the position marker for a
while.
+Initialize the system outside for receiving the radio wave
from the GPS satellite.
How to PerformNJEL0520S09011. Switch the navigation system mode to self-diagnosis by push-
ing both ªMAPº and ªMODEº switches at the same time for
more than 5 seconds.

GPS signal reception conditions are good. However, the position mark does not return to its proper
position.
+The system senses the vehicle location with an error of approximately 100 m (328 ft). Due to the limita-
tion of precision, the position marker may be inaccurate even if the GPS signal reception condition is good.
+The 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.
+When the vehicle is stationary, GPS data cannot be used to make system corrections.
Area designations on the map display and the BIRDVIEW
Tdisplay 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-494.]
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-488). 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 GUIDENJEL0526S03+If the present location or the destination location is displayed in the avoid area, it is not possible to search
routes.
+If the avoid area is set to wide range area, it may not be possible to find appropriate routes or search for
alternate routes.
+The 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.
+The automatic re-route function may sometimes require considerable time.
+Displayed route number and directional information at a highway junction may differ from the information
posted on the actual road signs.
+Displayed street name information at a highway exit may differ from the information posted on the actual
road signs.
+Street name information displayed on the enlarged intersection map may differ from the information posted
on the actual road signs.
