Abstract
A navigation device includes a platform having hardware including at least a user operation unit and a map database, and basic functions to control the hardware. The navigation device also includes an application processing unit for providing navigation services using the basic functions of the platform, and a platform-dependent unit for, when transferring information from the platform to the application processing unit, transferring the information in a constant format, and for, when transferring information from the application processing unit to the platform, transferring it in a certain format which depends on the platform. The map database holds map data in a predetermined recording format. The navigation device can further include a map-database-dependent unit for receiving map data, which is read from the map database by the platform-dependent unit, and for supplying the received map data to the application processing unit in the constant format. The navigation device can also include a user-interface-dependent unit for receiving data corresponding to a user's operation, which is read from the user operation unit by the platform-dependent unit, and for supplying the received…
