the Earth which has an unobstructed view of four or more GPS satellites.
The GPS is operated and controlled under the sole responsibility of the Government of the United States of America, who
are responsible for its availability and accuracy. It may purposely reduce the accuracy of the GPS signals so that the car may
swing. Any changes in GPS availability and accuracy, or in environmental conditions, may impact the operation of the
navigation software.
It is not a system failure under circumstances listed below:
Situations that can affect the GPS positioning:
When you are driving on a very steep road;
When you are driving on a spiral road, you will find that the floating point swings;
When you make a right/left turn to enter a road and that has parallel roads nearby (less than 55 yards distance), you
might find that the floating point may go to another road;
The guided distance may deviate from the actual distance rate;
When any of those situations occurs, the GPS satellite will automatically adjust the current position fix if you keep
driving.
Problems caused by map files:
Newly constructed road does not recorded in map file;
Opening of a new road and closure of an old road;
If there are only small lanes without a normal road near the destination, the system will only guide you to a place
near to your destination;
Turning instruction mismatch the real road condition;
No indication of direction or voice prompts about entrance/exit while guiding on highway/extap way;
Schematic map may mismatch real road conditions.
Places having difficulties to receive GSP signals:
In tunnels;
Between high buildings;
Under bridges;
In trees/forests.
