Communication navigation system and method, program storage device and computer data signal embodied in carrier wave

摘要

A communication navigation system is provided with: a communication navigation terminal ( 5 ) and a communication center apparatus ( 3 ) with a communication network ( 2 ) for connecting them. The communication navigation terminal is provided with a traveling locus recording device ( 36, 24 ) for preferentially holding a traveling locus recorded when a movable body is driving out of a service area of the communication navigation system; and a processing device ( 20 ) for performing a route search and the like on the basis of this preferentially held traveling locus.
