5 Grid 

road 

 

When driving in the place where the 
road is distributed in a gird manner 
and there are multiple roads nearby 
extending along the same direction, 
the map can match with the other 
roads, so that the position mark can be 
deviated from the current position.

When two roads are parallel (for 
example, there is another side road 
adjacent to the highway), the other 
road may be wrongly matched in the 
map; thus, the position mark may be 
deviated from the current position.

road 

Repair method

When continually running for a 
period of time, the vehicle will 
be correctly positioned again 
after the road is branched.

In the parking lot. 

 

When running in the parking lot or on 
the road that does not exist in the map, 
the current position of the vehicle may 
be marked on the closed road. When 
the vehicle returns to the road, the 
position mark point may be deviated 
from the correct position.

Steep mountain slope and incline. 

 

When parking on a slope road or in 
the case of the vehicle inclined, the 
error of angle of turn may be caused, 
so that the position mark point may be 
deviated from the correct position.

When the lane is frequently changed during driving, the position marking position may be 
deviated from the correct position.

Map data correlation 

 

(a)  When vehicle runs on new road 

or road which can't be shown on 
map screen, the map matching 
function can't make effect. 
Therefore, when other 
neighboring roads are matched, 
the position point will have a 
little deviation from correct 
position. 

(b)  If road shape and actual road 

stored on map data are different 
from actual road, the map 
matching function can't make 
effect. Therefore, when other 
neighboring roads are matched, 
the position point will have a 
little deviation from correct 
position.

11.3.6.5 Common fault symptom table of navigation 

Fault symptom 

Cause 

Disposal method 

1.  Error series number of main host is input 

when generating active code. It is 
necessary to update navigation map data. 

2.  When map disc has more than two 

versions, misuse of map disc may cause 
mismatching of map version whose active 
code is generated and map version copied 
into SD card. This will cause map version 
mismatching and activation operation can't 
be conducted. 

The map cannot 
be successfully 
activated. 

3.  When continuously operating multiple 

vehicles, if oil activation code in U disc 
isn't deleted and new activation code is 
loaded into SD card directly, it may cause 
error of file name and map can't be 
activated. 

Correctly update the 
navigation map data 

Navigation can 
receive the GPS 
signal, but the 
GPS does not 
synchronously 
move when the 
vehicle moves. 

The on-board navigation system is equipped 
with a built-in such devices as a gyroscope, etc 
which require the vehicle to travel a certain 
distance for paring the map data. 

Drive the vehicle at 
60km/h for a period of 
time, then perform 

Testing. 

1.  Input wrong address, such as some big 

hotel is input into small hotel. 

2.  Old name is input and name in map is also 

old, but this unit is renamed, or address is 
changed, etc. 

The destination is 
not found out in 
the map. 

3.  Some information related    to state 

security can't be shown in map, such as 
embassy, waterworks and military unit, 
etc. 

Refer to the Navigation 
System Operation Manual 
for correct operation.
