A tour schedule processor stores a tour schedule, in which a variety of transportation means are used, in a vehicle-installed data terminal and a personal digital assistant (PDA) such as a palm top computer, and enable the tour schedule to be carried out. A center console of a vehicle has a recess for receiving the PDA which retains the tour schedule. A data processor in the PDA transmits the tour schedule to a data processor in the vehicle-installed data terminal, which extracts and retains data related to the vehicle from the tour schedule. When a current position denotes transportation by the vehicle, a navigation unit of the vehicle-installed data terminal guides the vehicle. At the end of the guidance, the data processor of the vehicle-installed data terminal starts the PDA. The PDA then performs guidance. The PDA is removed from the recess, and guides the driver who is carrying the PDA. <IMAGE> |
