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.

+The enlarged intersection map may display an ªUnknown streetº message at some street intersections.
+Because of road configuration, etc. the guide may finish early. If this occurs, follow the marker to reach
your destination.
+Destination area side information (left side and right side) may differ from actual conditions because of
data error.
Unable to Set Destination, Way Point, and/or menu itemsNJEL0526S0301
Symptom Possible cause Repair order
Unable to search way points in
re-search modeA way point already crossed or determined to
have been crossed.If you desire to pass through a way point for a
second time, reperform route edit.
Turn list is not displayed.Route search does not occur.Set designation areas and perform route
search.
Car marker does not appear on recom-
mended route.Drive on the recommended route.
Route guide is canceled.Turn the route guide ON. (Push ªVOICEº
switch)
Automatic search does not func-
tion.Vehicle is not running on search object route
(road indicated by orange, brown or red line).Drive the vehicle on the search object route
or perform a manual route search. Note that
all routes will be re-searched at this time.
Unable to select detour route. Vehicle is not running on recommended route.Use the ªRE-ROUTEº mode to search again
or return to the recommended route.
Detour route search results are
identical to previous search.All possible conditions were considered, but
results are the same.This is not abnormal.
Unable to set a way point.More than five way points have been previ-
ously set (and not cleared).More than five way points cannot be specified
at the same time. Break down into smaller

No route is displayed.No object route is searched near destination
area.Adjust position to wide road (brown) near des-
tination area. In an area where traffic direction
is displayed separately, pay close attention to
the direction of travel. Set the destination area
and the way point over the road.

may be separated.Set the destination area to the general route
(indicated by a thick brown line). However,
even if the selected route is a major one,
appropriate route search data may not be
available.
LOCATION OF CAR MARKERNJEL0526S04+If the vehicle has been parked in a multi-level parking facility or underground parking facility, the car marker
position may be inaccurate immediately after exiting the parking facility.
+The GPS accuracy is within±100 m (300 ft). Even when receiving conditions are excellent, further posi-
tional correction may not occur.

+Some data may not be available for new buildings and other structures in a map.
GPS ANTENNANJEL0526S07+Do not place metal objects above the GPS antenna mounted on the rear parcel shelf. This will cause
interference with signal reception.
+Do not place mobile telephones or vehicle radio transceivers in close proximity to the GPS antenna
mounted on the rear parcel shelf. This may cause interference with signal reception.
