    • The Navigation Apparatus transmits to a server apparatus a current position, a destination, and an area of a geographical information stored in a geographic information memory part. The server apparatus receives them to calculate one or more potential routes from the current position to the destination; sets a potential passing-by point for each potential route in the area of the geographic information stored in the Navigation Apparatus; and transmits those potential passing-by points to the Navigation Apparatus. The Navigation Apparatus receives them to calculate traveling routes from the current position to the potential passing-by points and selects one of the potential passing-by points, thereby deciding the passing-by point as a temporary destination within the area of the geographic information stored in the Navigation Apparatus. In this way, the route navigation can be realized without increasing the memory capacity of the geographic information memory part of the Navigation Apparatus. Additionally, since only necessary information, such as the geographic information, passing-by points and the like, are transmitted and received, the communication cost can be reduced.
    • 导航装置向服务器装置发送存储在地理信息存储部分中的当前位置,目的地和地理信息的区域。 服务器装置接收它们以计算从当前位置到目的地的一个或多个潜在路线; 为存储在导航设备中的地理信息的区域中的每个潜在路线设置潜在的过去点; 并将这些潜在的经过点发送到导航装置。 导航装置接收它们以计算从当前位置到潜在过路点的行进路线,并选择潜在过路点中的一个,从而将存在的地理信息区域内的过境点确定为临时目的地 在导航装置中。 以这种方式,可以在不增加导航装置的地理信息存储器部分的存储容量的情况下实现路线导航。 此外,由于仅发送和接收诸如地理信息,过去点等必要信息,所以可以降低通信成本。
