Further, depending on the surrounding road conditions, for example, other intersections can be set in various ways within a range that is not mistakenly recognized as a guide point. Specifically, for example, in an area where there are intersection roads every 100, even if the first display switching determination distance TH1 is set to 100 m, other intersections are not mistakenly recognized as guide points, whereas the intersection road is 50 m. Then, there is a risk that other intersections will be mistakenly recognized as guide points. As a result, in areas where the crossing roads are every 50 m, it is desirable that the first display switching determination distance TH1 is 50 m or less.
