PURPOSE: A navigation method is provided to use only a small volume of data to be transmitted to the motor vehicle and ensure that driving instructions are output accurately for the position. CONSTITUTION: In a road map section for a journey from a starting point(S) to a destination(Z), the route runs via road points(WP1, A1, A2, WP2 and WP3) to the destination(Z). Turnoff maneuvers need to be made at road points(WP1, WP2 and WP3), whereas at A1 and A2 the journey continues without any turnoff maneuver. Preferably, only those road points, which are also turnoff points, are stored. The distance from the next turnoff point at which a turnoff maneuver is to be effected is determined by comparing the distance covered since the last turnoff point with a stored value for the road distance between the adjacent turnoff points. If a minimum value for the distance from the next turnoff point has not been reached, a driving instruction is output.
