An expandable multi-level intelligent vehicle highway navigation system (11) for a motor vehicle having an input device (34) that is adapted to load the segments (21) of a route into a memory means (32). A controller (30) receives a wheel pulse input (28) for distance and electric power (36) from the vehicle and controls the memory (32) and a plurality of displays (13) for displaying the segments (21) of the route, graphic symbols for vehicle direction and segment distance. The controller (30) may be adapted to control additional units such as infrared transceivers (58), RF transceivers (44), GPS devices (52), routing computers (48), map data bases (50), compass (56), etc. and various miscellaneous inputs (54) to build the basic unit into a more complex routing system.
