According to the invention described in claim 8, by using means having a GPS receiving function as the position detecting means, it is possible to realize a traffic time notification system using highly accurate position information.

According to the ninth aspect of the present invention, by using the transit time to the destination according to the first aspect as the predicted time of passing through the waypoint, the predicted time of passing through the waypoint can be accurately calculated. A traffic time notification system using a high value can be realized.
