Zusammenfassung:	In a communication system for downloading programs from a center (11) to in-vehicle terminals (21), a center can check whether downloading has been completed normally or a program is operating normally in an in-vehicle terminal. According to the timing of activating a downloaded program, an in-vehicle terminal (21) checks whether the program is activated to operate normally. The information is transmitted to the center (11). Based on the information, the center (11) becomes aware of the fact that downloading has been completed without any problem and that the program is operating normally in the in-vehicle terminal (21).
