PROCEDURE
CHECK CABIN
Check the cabin for any object that might interrupt radio reception or additional devices which use radio waves on the instrument panel. If such an object exists, remove it and check if the GPS mark reappears.
Tip: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.

CHECK SURROUNDINGS
