Abstract

A navigation method for a motor vehicle is described, the purpose of which is to display an arrow as a directional symbol on a windshield as a function of signals from a viewing direction recognition device, with the directional information being determined by a navigation device When approaching a turn-off to be selected, the arrow moves in the direction of the turn-off. In addition, the arrow becomes shorter and/or changes color and/or its flashing frequency. A rotation of the arrow on the windshield as a function of the stipulated route is also possible. The projection apparatus, to which the navigation device is connected, has means for placing the arrow in the field of vision of the driver.
