Abstract
Data for a map of a predetermined area is divided into a plurality of blocks, stored in an external memory medium such as a cassette tape, and loaded into a CPU when deemed necessary. The map as a whole or parts of the map can be arbitrarily selected and displayed through the operation of a keyboard, and vocal sight-seeing guidances corresponding to the displayed maps are simultaneously produced. Control of this multiple map system is effected by an electronic device having a microprocessor, and selected maps and necessary words are shown in displayed pictures by a display means, such as a cathode ray tube or the like.
