The user searches for a destination and uses the navigation system to display the route. The user sets the destination in the navigation system and follows the navigation system's guidance to drive to the destination.

In this case, if the function to display a map is not working properly due to the lack of the remaining memory, the destination cannot be displayed properly or the screen will stop. When there is not enough memory left, an event will be issued to notify the necessary applications in the system.

Then, in order to display the map correctly, the entire system will be automatically restarted and the user can use the navigation system normally, but before that, the necessary applications can take fail-safe actions.

A user starts the IVI and launches the radio. The radio function requests and obtains longitude and latitude information in order to obtain location information, and the user can listen to a radio station based on the current location.A user searches for a destination, launches the navigation application, and searches for the destination. To search for a route to the destination, the current location information is acquired. (To acquire the current location, the navigation service performs inter-process communication with a service that acquires location information, and obtains the information.)
