A vehicular system acquires a message or a file in an SOVD format compliant with SOVD communication specifications. The vehicle system includes a storage that retains process-target specifier information indicating association between a process-command based on the message or the file in the SOVD format and connection destination information enabling to specify a process-target corresponding to the process-command. When the process-command is accepted, the vehicle system refers to the process-target specifier information and specifies the process-target corresponding to the accepted process-command based on the connection destination information.
