11.3.6.6 Navigation Common Fault Symptom Table

Failure Symptoms

Reason

Approach

It can not successfully
activate the map.

1. When activating, entered the wrong serial
number for the navigation unit.

Update the navigation map data.

2. CD-ROM map has more than two versions,
CD-ROM with the wrong map, guide system
activation maps generated version and the SD
card map version is inconsistent, resulting in
map version does not match, can not activate.

3. Continuous operation on multiple vehicles, the
old U disk activation code is not deleted. directly
downloaded the new activation code to the SD
card, resulting in an error file name, resulting in
maps can not be activated.

Navigation is able to receive
GPS signals, but the GPS
does not synchronize with
vehicle moving

There are other built-in gyroscope devices. GPS
requires a certain driving distance for map data
matching.

Driving a vehicle at 60 km/h or more for some
time, and then test it.

It can not find the destination
on the map.

1. The input address is not accurate.

Refer to the navigation manual, operate
correctly.

2. Input is the old name, the map has the old
name, but the place has been renamed, or has
changed address.

3. Map information related to national security is
not shown on the map, such as embassies,
water plants, and military units.
