In the past, it has been difficult to update a function of software and correct its trouble for a vehicle-mounted device which once came onto the market, in the case that the device has no online update function in the software. Specifically, the update of function has been implemented by using update CDs and SD memories selling or distributing in the market in the past, therefore, there is a problem that such media is not circulated around users who are not registered as a user registration or people using a used car. Further, it has taken a lot of time to deliver an update notification by mail, or CD and SD memory by other delivery companies.
In a method of solving the above-mentioned problem, there exists a method referred to as an online update in which a program is downloaded via a network to update the program. For example, the update for the vehicle-mounted device providing an online update function can be notified to all of the vehicle-mounted devices coupled with a network via another network by using the configuration of online update as disclosed in JP-A-2003-122575 ([0002]-[0011]). Further, the update can be started immediately by requesting the update and receiving the notification from the user of vehicle-mounted device, therefore, it does not take a time for the start and delivery. As mentioned above, it is not required to select a time and location, for updating the program and data in the vehicle-mounted device providing the online update function in which the program and data are downloaded to implement the update, therefore, the update becomes easily.
