in the unit, display the track of the vehicle on the map screen and compare it with the actual road configu-
ration.

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.
–;
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.
Correction = 1 – A/B
A: Distance shown on the screen
B: Actual distance
YES or NO
YES >>
If adjustment is insufficient, perform adjustment again.

If any error is found in the map, please let us know.

Replace NAVI control unit.
NO >> Limit of the location detection capacity of the navigation system.
