Navigation System
WARNING: This page is about a different car, the 2012 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
Basic Operation
| Symptom | Cause | Remedy |
|---|---|---|
| No image is shown. | Display brightness adjustment is set fully to DARK side. | Adjust the display brightness. |
| No guide sound is heard. Audio guide volume is too low or too high. | Volume control is set to OFF, MIN or MAX. | Adjust the audio guide volume. |
| Audio guidance is not available while the vehicle is driving on a dark pink route. | System is not malfunctioning. | |
| Screen is too dark. Motion of the image is too slow. |
Temperature inside the vehicle is low. | Wait until the temperature inside the vehicle reaches the proper temperature. |
| Small black or bright spots appear on the screen. | Symptom peculiar to a liquid crystal display (display unit). | System is not malfunction. |
Vehicle Mark
| Symptom | Cause | Remedy |
|---|---|---|
| Map screen and BIRDVIEW™ Name of the place vary with the screen. | Some thinning of the character data is done to prevent the display becoming to complex. In some cases and in some locations, the display contents may differ. The same place name, street name, etc. may not be displayed every time on account of the data processing. |
System is not malfunctioning. |
| Vehicle mark is not positioned correctly. | Vehicle is transferred by ferry or by towing after its ignition switch is turned to OFF. | Drive the vehicle for a while in the GPS satellite signal receiving condition. |
| Screen will not switch to nighttime mode after the lighting switch is turned ON. | The daytime screen is selected by the "SWITCH SCREENS" when the last time the screen dimming setting is done. Switching between daytime/nighttime screen may be inhibited by the automatic illumination adjustment function. |
Perform screen dimming and select the nighttime screen by "SWITCH SCREENS". |
| Map screen will not scroll in accordance with the vehicle travel. | Current location is not displayed. | Press "MAP" button to display the current location. |
| Vehicle mark will not be shown. | Current location is not displayed. | Press "MAP" button to display the current location. |
| Accuracy indicator (GPS satellite mark) on the map screen stays gray. | GPS satellite signal is intercepted because the vehicle is in or behind a building. | Move the vehicle out to an open space. |
| GPS satellite signal cannot be received because an obstacle is placed on top of the instrument panel. | Do not place anything on top of the meter display (instrument panel). | |
| GPS satellites are not visible from current location. | Wait until GPS satellites are visible by moving the vehicle. | |
| 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 fitted or the system has been used on another vehicle. | 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 CONFIRMATION/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. |
Destination, Passing Points and Menu Items Cannot be Selected/Set
| 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 displayed. | 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 pink 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 recommended 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). However, the result is the same as that of the previous search. | Performed search with every conditions considered. 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 selected. | The vehicle is being driven. | Stop the vehicle at a safe place and then operate the system. |
Voice Guide
| Symptom | Cause | Remedy |
|---|---|---|
| Voice guide will not operate. |
NOTE:
Voice guide is only available at intersections that satisfy certain conditions (indicated by •
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 research 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 actual road pattern. | Voice guide may vary with the direction to which the vehicle is turn and the connection of the road to other roads. | Drive in conformity to the actual traffic rules. |
Route Search
| Symptom | Cause | Remedy |
|---|---|---|
| No route is shown. | No road to be searched is found around the destination. | Find wider road (orange road or wider) nearby and reset the destination and passing points onto it. Take care of the traveling direction 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 current 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 section. 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 area.) | 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 destination, 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. |
NOTE:
Except for the ordinance-designated cities. (Malfunctioning areas may be changed in the updated map disc.)
Examples of Current-Location Mark Displacement
Vehicle's travel amount is calculated by reading its travel distance and turning angle. Therefore, if the vehicle is driven in the following manner, an error will occur in the vehicle's current location display. If correct location has not been restored after driving the vehicle for a while, perform location correction.
| Cause (condition) -: While driving ooo: Display | Driving condition | Remarks (correction, etc.) | |
|---|---|---|---|
| Road configuration | Y-intersections | At a Y intersection or similar gradual division of roads, an error in the direction of travel deduced by the sensor may result in the current-location mark appearing on the wrong road. | If after travelling about 10 km (6 miles) the correct location has not been restored, perform location correction and, if necessary, direction correction. |
| Spiral roads | When driving on a large, continuous spiral road (such as loop bridge), turning angle error is accumulated and the vehicle mark may deviate from the correct location. | ||
| Straight roads | When driving on a long, straight road and slow curve without stopping, map-matching does not work effectively enough and distance errors may accumulate. As a result, the vehicle mark may deviate from the correct location when the vehicle is turned at a corner. | ||
| Zigzag roads | When driving on a zigzag road, the map may be matched to other roads in the similar direction nearby at every turn, and the vehicle mark may deviate from the correct location. | ||
| Roads laid out in a grid pattern | When driving where roads are laid out in a grid pattern, or where many roads are running in the similar direction nearby, the map may be matched to them by mistake and the vehicle mark may deviate from the correct location. | ||
| Parallel roads | When two roads are running in parallel (such as highway and sideway), the map may be matched to the other road by mistake and the vehicle mark may deviate from the correct location. | ||
| Place | In a parking lot | When 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 location. 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 travelling about 10 km (6 miles) the correct location has not been restored, perform location correction and, if necessary, direction correction. |
| Turntable | When the ignition switch is OFF, the navigation system cannot get the signal from the gyroscope (angular speed sensor). Therefore, the displayed direction may be wrong and the correct road may not be easily returned to after rotating the vehicle on a turntable with the ignition OFF. | ||
| Slippery roads | On 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. | ||
| Slopes | When parking in sloped garages, when travelling 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 data | Road not displayed on the map screen | When 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 deviate 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 vehicle mark may deviate from the correct road. | ||
| Vehicle | Use of tire chains | When tire chains are used, the mileage is not correctly detected, and the vehicle mark may deviate from the correct road. | Drive the vehicle for a while. If the distance still deviates, adjust it by using the distance adjustment function. (If the tire chain is removed, recover the original value.) |
| Precautions for driving | Just after the engine is started | If 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 stopping, 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 detection, and may cause the vehicle mark to deviate from the correct road. | If after travelling about 10 km (6 miles) the correct location has not been restored, perform location correction and, if necessary, direction correction. | |
| How to correct location | Position 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 correction.
|
| Direction when location is corrected | If the accuracy of location settings during correction is poor, accuracy may be reduced afterwards. | Perform direction correction. | |
Location Correction by Map-Matching is Slow
- The 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.
- Because map-matching operates on this principle, when there are many roads running in similar directions in the surrounding area, no matching determination may be made. The location may not be corrected until some special feature is found.
Name of Road is Not Displayed
The current road name may not be displayed if there are no road names displayed on the map screen.
Contents of Display Differ for Birdview™ and the (Flat) Map Screen
Difference of the BIRDVIEW™ screen from the flat map screen are as follows.
- The current place name displays names which are primarily in the direction of vehicle travel.
- The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the (flat) map display.
- The conditions for display of place names, roads, and other data are different for nearby areas and for more distant areas.
- Some thinning of the character data is done to prevent the display becoming too complex. In some cases and in some locations, the display contents may differ.
- The same place name, street name, etc. may be displayed multiple times.
Vehicle Mark Shows a Position Which is Completely Wrong
In the following cases, the vehicle 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 direction correction.
- When location correction has not been done
- If the receiving conditions of the GPS satellite signal is poor, if the vehicle 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 being towed
- Because calculation of the current location cannot be done when traveling with the ignition off, for example when traveling by ferry or when being towed, the location before travel is displayed. If the precise location can be detected with GPS, the location will be corrected.
Vehicle Mark Jumps
In the following cases, the vehicle 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 vehicle mark are different when map matching is done, the vehicle mark may seem to jump. At this time, the location may be "corrected" to the wrong road or to a location which is not on a road.
- When GPS location correction has been done
- If the current location and the vehicle mark are different when the location is corrected using GPS measurements, the vehicle mark may seem to jump. At this time, the location may be "corrected" to a location which is not on a road.
Vehicle Mark is in a River or Sea
The navigation system moves the vehicle mark with no distinction between land and rivers or sea. If the vehicle mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
Vehicle Mark Automatically Rotates
The system wrongly memorizes the rotating status as stopping when the ignition switch is turned ON with the turntable rotating. That causes the vehicle mark to rotate when the vehicle is stopped.
When Driving on Same Road, Sometimes Vehicle Mark is in Right Place and Sometimes it is in Wrong Place
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually. Depending on the road traveled and the operation of the steering wheel, the location detection results will be different. Therefore, even on a road on which the location has never been wrong, conditions may cause the vehicle mark to deviate.
