A navigation system for a motor vehicle includes at least one storage
device, at least one navigation map being stored on each storage device,
which is read out using a reading device. Associated with the reading
device is a changeover device for exchanging storage devices that are to
be read out by the reading device. A navigation map and information
regarding the instantaneous position of the motor vehicle are displayed
to a vehicle occupant via a display device. A control device for the
changeover device controls the changeover device so that a point in time
for changing over the storage device is identifiable so that during the
changeover operation of the storage device, a deviation of the motor
vehicle from the route segment currently being traveled is improbable
based on the current navigation data of the motor vehicle.
