A method for displaying driving instructions, wherein the surroundings of a vehicle are recorded in a field of vision of a driver by a vehicle camera and augmented by driving instructions on a navigation display unit as a function of a destination and current position of the vehicle, comprising:

  • determining a current geographical position of the vehicle camera in three dimensions, a current orientation of the vehicle camera being determined in a horizontal plane and a current angle of inclination of the camera viewing direction relative to the horizontal being determined;

    deriving a particular position of a navigation point from a three-dimensional map to generate driving instructions;

    calculating at least one viewing angle in a vertical dimension, at which the navigation point is viewed from the vehicle camera as a function of the current angle of inclination; and

    adjusting display of the driving instructions as a function of the at least one viewing angle at least in the vertical dimension on the navigation display unit.
