A method for recording and storing a route of a motor vehicle in an undigitized area of a vehicle navigation system comprises determining a first position of the motor vehicle using a Global Positioning System. This first position is then recorded in the vehicle navigation system. A second position of the motor vehicle is determined after the motor vehicle has traveled a predetermined distance from the first position. This second position is also recorded in the vehicle navigation system. The first position is then connected to the second position in order to form a route in the vehicle navigation system. The route has a segment in an undigitized area of the vehicle navigation system. The route is then stored in the vehicle navigation system and may be retrieved at a later time.
