Abstract: In order to find a parked vehicle with the aid of a separate navigation device which is independent of the vehicle, a close-range communication connection is established between a vehicle device permanently located in the vehicle and a portable storage device. The communication connection is maintained as long as the storage device is at close range. Collapse of the close-range communication connection between the storage device and the vehicle device is used as the criterion for storing current position data of the vehicle. A navigation device which is in the form of a separate device and contains navigation software and suitable electronic navigation maps, reads out the current position data and is used for navigation to the parked vehicle.
