Abstract
When a user selects an item from a menu displayed by a display unit of a vehicular terminal, a control unit of the vehicular terminal receives information data and location data corresponding to the information data from an information center and stores the data inside a database. After receiving present position data from a present position detection unit, the control unit determines location data that is nearest to the present position from among location data stored in the database. Then, the control unit drives the display unit to display the information data corresponding to the extracted location data, thus simplifying the selection process the user needs to perform to obtain the desired information.
