Abstract

When of a map or the like is displayed on the basis of an information read from a recording medium, the display can be preferably performed with little waiting time even when the apparatus is activated or when the recording medium is replaced.

For example, a predetermined information is saved in a non-volatile memory (18) immediately before the power supply is turned off or the recording medium is replaced, and the predetermined information saved in the non-volatile memory (18) when the power supply is turned on or a now recording medium is loaded to perform a desired display process based on the predetermined information thus read.
