ABSTRACT:
An electronic equipment system includes a housing20and a plurality of modules31to35,which are removably built in and fixed to the housing20.The modules31to34includes a liquid crystal display31a; a graphic control circuit32a1and a navigation control circuit32a2;an MD unit33a; and a CD unit34a, respectively. The module35is formed through integration of control sections, such as constant-voltage circuits for power supply, which achieve a function that is common among the graphic control circuit and the navigation control circuit, the MD unit, and the CD unit. Thus, it becomes possible to replace only necessary one among the modules31to34,thereby reducing cost necessary for upgrading of the system.
