The present invention provides a system for automatically registering destination
of visit or a normally stationed spot to a mobile information system such as car
navigation system. A position information detected by position detecting means
101 is stored in position storage means 102. From the position information
or from pattern of moving loci stored in the position storage means 102,
the position recognizing means 103 recognizes a place frequently visited
or a normally stationed spot of the system, and these are registered automatically
as registered destination or a normally stationed spot (owner's own home). Thus,
the destination frequently visited can be registered without performing specific
operation. The registered position can be used as a place of destination for searching
a desirable route for the vehicle. Also, by recognizing the normally stationed
spot, theft can be detected.
