To provide a suitable number of display fields (e.g. ARRIVAL; TIME; etc.), each of which characterizes and identifies the significance or import or meaning of a displayed numerical value on a display device (16), the display fields are associated in groups or sets (11-15; 42-45) having a particular geometric position (columns; segmental), and a plurality of keys (21-25) are provided with each key being associated with a group or set of the display fields, and connected to a counter (61) to select a particular one of the display fields within the group or set by the number of key operations, the numerical value associated with the display field then being displayed on the numerical display (16). The display and keys are connected to a computer (62) which provides the output data for the numerical indicator (16); an input/output control switch (26) is provided to change the function of the display group selection keys (21-25) to permit data entry into the computer (62), for example of speed limit, driving distance, and the like.
