摘要 |
A license management device receives a license issued by a license issuing device. The license management device transmits the received license to a navigation system for receiving the license, and stores the received license in a memory device. When the license to be acquired cannot be acquired, the navigation system requests the license issuing device to send the license. The license management device reads the license from the memory device, and transmits the license to the navigation system.
