<p>A navigation system, a user terminal, a navigation device (14), and an information recording method program that can reduce communication time. The system comprises compression means for compressing at least one of a plurality of sets of information generated by dividing the information based on priority, to create compressed data and compressed data transmission means for transmitting the compressed data to the navigation device (14). In this case, because the compressed data is created by compressing, based on the priority, at least one of a plurality of sets of information generated by dividing the information based on the priority, the communication time can be reduced. Therefore, the battery load is reduced. <IMAGE></p> |
