Abstract: The present invention includes a navigation process and a navigation system for a vehicle, especially a motor vehicle, a ship or aircraft, for navigating the vehicle from a starting position to a destination, in which a predetermined destination and, if necessary, a starting position are input into the navigation system. In this navigating method one or more predetermined numbers designating the predetermined destination and, if necessary, the starting position are input to the navigation system; then the one or more numbers are correlated with one or more position addresses from a position address list provided in a memory device and are read out from the memory device; and the one or more position addresses output from the memory device are assigned as the destination and, if necessary, the starting position. Preferably the numbers input to the memory device are telephone numbers of telephones located at the different destinations and the memory device includes a CD-ROM.
