摘要：
A communication type navigation apparatus can communicate with a server device via a communication path. The navigation apparatus requests route search, and the server device executes route search to produce route information of a searched route. Then, the meshes necessary to travel along the searched route are determined, and the navigation apparatus obtains necessary mesh data from the server device. The navigation apparatus may request newer mesh data to the server device based on the updating information of the mesh data. By appropriately determining the mesh data to be and not to be downloaded from the server device, the communication cost necessary for obtaining the mesh data can be saved.
