<P>PROBLEM TO BE SOLVED: To easily prevent operation errors in cooperative software due to a version number difference between software of a communication terminal and software of a device with no communication function. <P>SOLUTION: A communication terminal 100 determines whether cooperative operation is possible between communication terminal cooperative software having a version number and on-vehicle device cooperative software having a version number obtained from an on-vehicle device 200. When determining that cooperative operation is impossible, the communication terminal obtains any one of on-vehicle device cooperative software and communication terminal cooperative software having a version number for enabling cooperative operation from a server 300. When the communication terminal cooperative software is obtained, the communication terminal changes the current communication terminal cooperative software to the obtained communication terminal cooperative software. When the on-vehicle device cooperative software is obtained, the communication terminal outputs the on-vehicle device cooperative software to the on-vehicle device 200, and the on-vehicle device 200 changes the current on-vehicle device cooperative software to the output on-vehicle device cooperative software. <P>COPYRIGHT: (C)2013,JPO&INPIT |
