Abstract
In the case of a system for marking a region within an image of a road map detail displayed on a vehicle video screen, a regional location can first be selected by a control element. The region, which represents one of several administrative levels, can be constantly fixed via an enter function of the control element. The administrative level and thereby the size of the region can be changed by a rotational movement of the control element, which can be rotated about a longitudinal axis.
