11.3.6 Diagnostic information and steps 

11.3.6.1 Visual inspection 

– 

Inspect installed aftermarket equipment that may affect the operation of the audio system. 

– 

Inspect components easy to access system to identify whether there is a significant damage 
that may lead to the fault. 

– 

For the fault that all speakers don’t work, the inspection can emphasize on some positions of 
speaker circuit which are easy to create short-circuit to the ground 

– 

If a single speaker is inoperative, it may because the audio channel is shielded, causing a 
single channel inoperative. It is not an audio system malfunction. Refer to the audio system 
instructions in the user manual. 

– 

For the fault which can’t be guided into the navigation interface, it may be caused by the 
situation that the customer doesn’t install SD card with navigation map data, or the card is 
not special for the purpose use. Firstly, check whether the performance of the SD card and 
the internal data are normal. 

11.3.6.2 System diagnostic description 

1.  When vehicle is running, it is strictly forvbidden to operate this navigation system to avoid 

traveling safety caused by distracting attention. 

2.  When vehicle is running on unflat road, huge jolt may cause sound jumping. 

3.  GPS positioning of vehicle entertainment navigation system may be affected by weather 

condition and application places (high building/ tunnel/ basement/ forest), and most of GPS 
can't be used indoor and basement, and GPS signal also can't penetrate high-story buildings 
and vehicle heat insulation film or similar products containing metal element. 

4.  The GPS results provided by the vehicle entertainment and navigation system is only for the 

driver's reference. If it is abnormal, please travel on the actual road conditions. 

5.  The electronic navigation geo data provided by the vehicle entertainment and navigation 

system is only for common reference and cannot provide high accuracy positioning and route 
planning. The voice prompts and intersection information are the recommendation result 
calculated in the best path based on the electronic map database for pilot reference only; and 
the driver must abide by the local traffic rules. 

6.  When driving, keep the voice instruction volume at the appropriate level to ensure you can 

perceive the road and vehicle conditions for guarantee safe travelling. 

7.  Avoid excessive moisture and dust. Do not have the navigation unit get in contact with water. 

This will cause electric shock, firing or other damages. 

8.  A too high or too low temperature will interfere with the normal functioning. If the vehicle is 

closed and the engine parks for a long time in direct sunlight or cold place, the vehicle 
becomes particularly hot or cold; moreover, the entertainment navigation system may work 
abnormally in this environment. Once the in-vehicle temperature returns to the normal range, 
the normal function can be restored. If beyond recovery, please contact with the after-sale 
service center authorized by Geely Automobile for maintenance. 

9.  If the vehicle entertainment and navigation system malfunctions (power failure, no image and 

no sound) or is in an abnormal status (containing foreign matters, water permeation, smoke 
leak or abnormal smell), do not open the casing, disassemble the unit or lubricate the 
movable parts. Immediately cut off the power and contact with the service center authorized 
by Geely Automobile for inspection.

11.3.6.3 Navigation usage precaution 

1.  Due to there is difference between each vehicle, when initially using navigation system, there 

should have a period for correction, so that the vehicle can be positioned more accurately. In 
the traveling process, the system will automatically and dynamically corrects. 

2.  If start vehicle after the vehicle stops for a long time, the time navigation system receives 

GPS signal and re-positioning is longer. Generally, positioning can be successfully finished 
within 3 min in signal strong area. 

3.  If GPS in located in places where GPS signal receiving may be affected: such as high 

buildings on both sides of road, big tree besides road, place under overpass, underground 
parking garage, place inside tunnel. At this moment, GPS signal can't be received, and 
positioning effect may also has error. 

4.  Sometimes the chip security module may fail to identify whether the vehicle is on an elevated 

road or the ground. After a period of time, the vehicle will be repositioned correctly after the 
road is branched. 

5.  If the vehicle runs on one of two parallel roads close to each other which run in the same 

direction (e.g. main road and auxiliary road), the vehicle may be positioned as runnign on the 
other road. After a period of time, the vehicle will be repositioned correctly after the road is 
branched. 

6.  A high turning speed or travelling on areas other than the middle may result in slight lagged 

or intermittent positioning. If the turned road has side road, it may be positioned on the side 
road. After a period of time, the vehicle will be repositioned correctly after the road is 
branched. Keep running at a lower constant speed when turning, thereby reducing the 
occurrence of such problems. 

7.  To avoid excessive no-effect voices and the failure to give out voice prompt at some curves: 

no fork junction exists at this turning point or the class of the turning point is excessively 
different from that of the fork junction. 

8.  During the turning process, the navigator will ask you to "turn to y at the xth crossing" to 

help the vehicle select the correct route if the road to be accessed is neighbored with other 
parallel roads in the same direction. One condition easily incurred is side road; at this time, 
prompt to regard the side road as the road junction. 

9.  To avoid plugging and removing the SD card when the navigation system is not turned off 

which will result in the damage and loss of the map file system on the SD card and in turn the 
failure of the navigation system to normally read the map file for navigation, it is prohibited 
to plug and remove the SD card when the navigation system is still on.

11.3.6.4 Localization revision of special road condition under the navigation non-fault status 

Notes: 

The following situations listed are not the fault phenomenon of navigation; if meeting the similar 
problem during maintenance, do a reasonable explanation to customer after commissioning 
validation. 

Diagnostic steps: 

1 

Y fork in the road 

 

On Y-shaped fork road or similar 
transition fork road, the error 
accumulated by the sensor in the 
running direction may result in the 
current position mark present to the 
error road.

2 

Replace the spiral road. 

 

When driving on the larger and 
continual spiral road (such as annular 
overpass and the like), the error of 
angle of turn will be accumulated, and 
the position mark may be deviated 
from the current position. 

NL11-2026b

Repair method

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

When turning a corner after running straightly 

 

When driving on a longer straight 
road with smaller stop bending, the 
map can not sufficiently and 
effectively match, thereby 
accumulating the distance error. Thus, 
the position mark may be deviated 
from the current position when the 
vehicle turns a corner. 

NL11-2027b

 

4 

Zigzag-shaped round-trip route 

 

When driving one a zigzagged road, 
the map may be matched with the 
other adjacent road in the same 
direction during turning a corner at 
every turn, so that the position mark 
may be deviated from the current 
position. 

NL11-2028b

Repair method

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

 

Repair method

When continually running for a 
period of time, the vehicle will 
be correctly positioned again 
after the road is branched. Keep 
running at a lower constant 
speed when turning, thereby 
reducing the occurrence of such 
problems.
