In this case, it is impossible for the system
to use GPS positioning.
In tunnels or enclosed parking
garages
your vehicle may differ from the position displayed on the map screen.
! If you make a shallow turn.

long time, your vehicle’s actual position
and the current position mark on the map
diverge considerably or do not be updated.
In such case, once GPS reception is restored, accuracy will be recovered.
Conditions likely to cause
noticeable positioning errors
For various reasons, such as the state of the
road you are traveling on and the reception
status of the GPS signal, the actual position of
