A navigation device serves for the self-sufficient destination guidance for street vehicles. At the beginning of a trip, the destination vector is input by way of an input device in the form of destination coordinates (x,y). During the trip, the path traversed is continuously determined in terms of magnitude and direction, with a dead reckoning navigation device. A destination vector is continuously determined from these measured path vectors and the input relative destination coordinates and is displayed in the field of vision of the driver with a display device.
