ABSTRACT:
An electronic apparatus includes an input line connectable to a supply source for vehicle information, a data transmitting and receiving unit for transmitting and receiving data, a current memory for storing vehicle information from the input line, a last memory for previously stored vehicle information, and a state-change judging unit for comparing vehicle information stored in the current memory and vehicle information stored in the last memory to determine whether the vehicle information has changed. When the vehicle information has changed, state-change data is transmitted to other electronic apparatuses through the data transmitting and receiving unit. The same vehicle information is thus shared by all the electronic apparatuses.
