Abstract

An apparatus (40) codes and stores cartographic data and general information relative to an area. A storage apparatus (31) transfers them after payment to memory media (1). An inboard apparatus (2) receives memory media, selects a route and provides driving indications in order to guide the vehicle in said route and general information in correlation with conspicuous points of the followed route.
