PROCEDURE
1. |
CHECK CABIN |
(a) Check the cabin for any object that might interrupt radio reception on the instrument panel. If such an object exists, remove it and check if the vehicle position mark returns to the appropriate position.
HINT:
The GPS uses extremely faint radio waves originating from satellites. If the signal is interrupted by obstructions or other radio waves, the GPS may not be able to properly receive the signal.
OK:
After driving for a while, the vehicle position mark returns to the appropriate position.

CHECK SURROUNDINGS |
(a) Check if the vehicle is in a location where GPS signal reception is poor. If the vehicle is in such a location, move the vehicle and check if the vehicle position mark returns to the appropriate position.
HINT:
The GPS uses 24 satellites in 6 orbits. At any point in time, 4 satellites should be able to pinpoint your vehicle. However, GPS signals may not reach the vehicle due to influence from the surroundings, vehicle direction and time. For examples, see the following illustration.
