An electronic guide device, used preferably as a guide to cities or towns, which has all selection functions distributed over two operational-control areas on both sides of an LCD display for determining the location of geographic objects of a predetermined type and the most favorable routes to reach them; geographic objects of a specifiable type and of geographic areas being selectable via a first control panel from indexes, and grid squares being selectable via a second or third control panel. The device displays a geographic map capable of being moved and zoomed in on underneath a cursor and a scale, and is equipped with its own energy source, as well as with a circuit arrangement having a read unit, and an opening for disk-shaped recording media, a bus, and a microcomputer for determining location and for processing and supplying additional information.
