A user inputs a position of a registration point by using an input device of an on-vehicle navigation device. A navigation ECU transmits the position of the registration point as a maintenance request to an information center. A center control section reads from a facility information memory section facility information of a facility existing at the position of the registration point and returns the facility information as maintenance data to the device. In the vehicle, new registration point data including the position of the registration point and the facility information is stored in a customizing information memory section. The user need only perform a simple operation, e.g., inputting of the position in order to obtain rich and detailed information. Furthermore, the registration point data in the memory section is appropriately updated with the updated information of the information center by using data communication with the information center.
