A GPS sensor 2 receives the position information. A memory 5 stores the information. A data processor 4 receives the position information and radio wave information via a controller 31 in a predetermined period, decides whether the field intensity of the received radio wave indicates the position is outside a service area, updates the position information obtained from the GPS sensor at the time when the decision result indicates the position is inside the service area, and records the information in the memory as final position data inside the service area. The controller 3 determines the field intensity of the received radio wave by the data processor for starting a communication, and, if the field intensity indicates the position is outside the service area, shows the present position obtained by the GPS sensor and the final position inside the service area based on the final position data inside the service area on a map of a display 32. <P>COPYRIGHT: (C)2004,JPO&NCIPI
