Radio Wave from GPS Satellite Is Not ReceivedINFOID:0000000003533766
1.CHECK ENVIRONMENT
Check if any metal object that intercepts radio waves or an object that emits radio waves (such as a portable
phone) is located near the GPS antenna. Check if the vehicle is shielded by a building.
OK or NG
OK >> System is not malfunctioning. The GPS antenna may not be able to receive radio waves from the
GPS satellite if it is shielded by metal object or an object emitting radio waves is placed near it.
NG >> GO TO 2.
2.SELF-DIAGNOSIS
Perform “Self-diagnosis mode” of the self-diagnosis function. Refer to AV-101, "
Self-Diagnosis Mode (NAVI)".
OK or NG
OK >> Replace GPS antenna. Refer to AV-145, "Removal and Installation".
NG >> Check the malfunctioning parts.
Driving TestINFOID:0000000003533767
1.DRIVING TEST 1
1. Scroll the map screen to display the area to make correction. Press “ENTER” and select “CURRENT
LOCATION CORRECTION”.
2. Correct direction of the vehicle mark.
3. Perform the distance correction of the "CONFIRMATION/ADJUSTMENT" mode.
Note: Normally, adjustment is not necessary because this system has automatic distance correction func-
tion. However, when a tire chain is fitted, adjustment in accordance with the tire diameter ratio must be
made.
4. Are symptoms malfunctioning to the AV-137, "
Example of Symptom Judged Not Malfunction" after driving
the vehicle?
YES or NO
YES >> Limit of the location detection capacity of the navigation system.
NO >> GO TO 2.
2.DRIVING TEST 2
• Did any malfunction occur when the proper test in the following test patterns is performed?
• Test pattern
Driving test finds the difference between the symptoms monitored with and without each sensor.
- Test pattern 1: Test method with no GPS location correction
Disconnect GPS antenna connector connected to the NAVI control unit. Accurately adjust the current loca-
tion and the direction, then drive the vehicle.
- Test pattern 2: Test method with no map-matching
Accurately adjust the current location and the direction. Eject the map DVD-ROM from the NAVI control unit
with ignition switch turned to OFF, then drive the vehicle. After driving, insert the map DVD-ROM back in the
unit, display the track of the vehicle on the map screen and compare it with the actual road configuration.
• Sample tests
- matching or by GPS>
Perform test pattern 1.
-
Perform test pattern 1 & 2.
Compare the track of the vehicle on the map screen and the actual road configuration. For fairly accurate
tracking, plotting shall be made every several hundred meters (feet).
-
Perform test pattern 1 & 2.
Drive on a road of which distance is accurately known (by utilizing distance posts on a highway). Calculate
the rate of change (increased/decreased) of the distance by comparing with the actual distance.

NAVIGATION SYSTEM
PLACE AND SOMETIMES IT IS 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.
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.
ALTHOUGH GPS RECEIVING DISPLAY IS GREEN, VEHICLE MARK DOES NOT RETURN TO
CORRECT LOCATION
• The GPS accuracy has an error of approximately 10 m (30 ft). In some cases the current-location mark may
not be on the correct street, even when GPS location-correction is done.
• The navigation system compares the results of GPS location detection with the results from map-matching
location detection. The one which is determined to have higher accuracy is used.
• GPS location correction may not be performed when the vehicle is stopped.
NAME OF CURRENT PLACE IS NOT DISPLAYED
The current place name may not be displayed if there are no place 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.
