11.3.3.3 Self-Navigation

When the vehicle is traveling to an underground tunnel,
between high-rise buildings, under highway bridges, it may not
receive GPS satellite signals, the system can automatically
enter the self-navigation mode. At this point the vehicle speed
sensor detects the vehicle, the vehicle microprocessor
calculates the distance. Gyro sensor directly detects the
direction change and moving forward status. For example,
when the vehicle is traveling in the ditch like Hill Road, round
shape bridge, skidding on snow, all these curves cause
positioning errors. Only the gyro sensor and microprocessor
calculations can get the correct vehicle location. However, the
positioning accuracy is far below the GPS positioning
accuracy.

11.3.3.4 Map Matching Techniques

Microprocessor electronic map is identified by the node-based
data.

FE11-5204b

There are discrepancies between the GPS satellite navigation
and self-navigation devices detected vehicle location and
direction and the actual driving route. To correct these errors,
the map-matching techniques are used. The microprocessor
correct the errors electronic map errors and automatically
adjust.

Map database stores roads, road maps and urban transport
map. Before driving, input the city, streets, place names, etc.
through the input interface. Through satellite signals systems,
the processor determines the direction and the best route
according to vehicle speed sensors, gyro sensors measured
data. During driving, driver can observe the screen to get the
current location. Display can also show the distance remaining
to reach the destination. At the same time prompts the related
information through audio voice output to the driver.

11.3.6 Diagnostic Information and Procedures
11.3.6.1 Visual Inspection

–

Check installed the after market equipment that may affect audio system operation.

–

Check the easy to access system components to identify whether there is a significant damage or a potential malfunction.

–

For all speakers inoperative malfunction, focus on easy to short to ground circuits, such as the rear compartment speaker wiring
harness connector, as it will help with quick diagnostic.

–

For one speaker inoperative malfunction, it may be because user accidentally shield one channel, making a single channel
inoperative. this is not a sound system failure. Refer to the user manual for sound system instructions.

–

For unable to enter the navigation interface malfunction, it may be because the SD card with map is not installed or the SD card
is not a dedicated card. Check the SD card performance first, whether the internal data is normal.

11.3.6.2 System Diagnostics Description

1. When driving, driver can not watch DVD or operate the navigation system, to avoid distraction affecting driving safety.

2. This vehicle entertainment navigation system can play CD-DA, CD-ROM, CD-R, CD-RW, VCD, DVD-ROM, DVD Recordable

disc.

3. The machine can only play the normal 12CM diameter disc. Do not use other disc, otherwise the disc may not eject or it cause

no damage to the player.

4. Do not use any solvents, such as the commercially available cleaners, anti-static spray cleaning disc.

5. Keep the vehicle and the disk clean, avoid the dust adhering to the laser head, resulting in a reduced playing disc ability, and

ultimately reduce the laser head life.

6. On the rough road, the sharp jolt could cause the sound jump.

7. The entertainment navigation system GPS positioning will be affected by the weather and the location (tower / tunnel / underpass /

tree). Most GPS can not be used indoor and in the basement location. GPS the signal can not penetrate the high-rise buildings
and metal-containing components of automotive insulation film or similar products.

8. Vehicle entertainment navigation system GPS positioning result is only for driver reference only. If abnormal, please drive

according to the actual road conditions.

9. Vehicle entertainment navigation system navigation electronic map data only provides general access information. it can not

provide high-precision positioning and the path planning. Voice prompts and the intersection information are based on the digital
map database the best path calculation results, and are for reference purposes only, the driver must abide by the rules of the
road.

10. Keep the volume at an appropriate level in order to be able to feel the situation of roads and vehicles to ensure road safety.

11. Avoid excessive moisture and dust. Do not let the navigation unit contact water, which will lead to electric shock, fire or other

damage.

12. When the vehicle inside temperature is low, do not use entertainment navigation system immediately after turning on the heater.

The entertainment navigation system disc or the player may be condensed with water. If there is condensation on the optical
components, stop using the entertainment navigation system disc playback function for about 1h. The condensation will
disappear naturally, and then it can be normally operated.

13. Very high or very low temperatures can interfere with normal function. If the engine is shut down, and the vehicle is parked under

the direct sun or at a cold place under for too long, the vehicle inside may become very hot or very cold. In this environment
entertainment navigation system may work properly. Once the temperature inside the vehicle is back to the normal range, the
normal function can resume . If it does not, please contact the authorized service center for repair.
