Yesterday morning was relatively cold and cloudy and on turning on the car the
navigation suggested that the car was in the ocean and that the speed limits
were unknown. This did not change on driving to an area with phone reception.
It has corrected itself today. So, the location sensing is almost certainly
from a GPS receiver rather than its SIM card.
