1. A navigational device for determining a guide route, comprising:
- present position detecting means for detecting present position;
means for searching for a first route from a starting point or from the detected present position to a destination or neighborhood thereof, based upon memorized map information;
means for searching for a second route from the starting point or the detected present position to the destination or neighborhood thereof, based upon locus data related to at least one road or intersection learned, by said detecting of present position, in previous travel through said at least one road or intersection;
outputting the first route and the second route, with the first route distinguished from the second route where the first and second routes do not overlap each other.

Abstract
Plural guide routes to a destination are found based upon different bodies of road (intersection) information, one of these plural guide routes is selected, and guidance to the destination via the selected route is output. One of the bodies of road (intersection) information is memorized map information and another body of road (intersection) information is related to roads or intersections which have been passed through before.

8. A navigational device for determining a guide route, comprising:
-
present position detecting means for detecting present position; first search means for searching for at least one first route from a starting point or the detected present position or neighborhood thereof to a destination or neighborhood thereof, based upon memorized map information; second search means for searching for at least one second route from the starting point or the detected present position or neighborhood thereof to the destination or neighborhood thereof, based upon locus data related to at least one road or intersection learned, by said detecting of present position, in previous travel through said at least one road or intersection or the memorized map information; selection means for selecting a first route or a second route; guidance means for providing guidance for the selected route from the starting point or the detected present position or neighborhood thereof to the destination or neighborhood thereof. - View Dependent Claims (9, 10, 11, 12, 13, 15, 27, 28)

16. A navigational device for searching a route, comprising:
-
present position detecting means for detecting present position; first search means for searching for a first route from a starting point or a detected present position to a destination or a neighborhood thereof, based upon memorized map information; storage means for storing locus data related to at least one road or intersection learned, by the detecting of present position, in previous travel through said at least one road or intersection; second search means for searching for a second route near the first route based upon the stored locus data; and output means for outputting the first route and the second route, and for distinguishing between the first and second routes where the first route and the second route do not overlap each other. - View Dependent Claims (18, 19, 20)

17. A computer readable storage medium containing, encoded thereon, a program comprising:
-
searching to determine a first route from a starting point or a present position to a destination or neighborhood thereof based upon memorized map information; storing locus data related to at least one road or intersection which has been passed through before; searching to determine a second route near the first route search based upon the stored locus data; and outputting a display of the first route and the second route, in a manner distinguishing the first route from the second route where the first and second routes do not overlap each other.

21. A navigational device for searching for a route, comprising:
-
first search means for searching for a first route from a starting point or a present position to a destination or neighborhood thereof, based upon memorized map information; means for storing locus data related to at least one road or intersection learned, by the detecting of present position, in previous travel through said at least one road or intersection; second search means for searching for a second route near the first route based upon the locus data; and output means for outputting a display of the first route and of the second route, distinguishing between roads used for the searching and roads not used for the searching. - View Dependent Claims (23, 24, 25)

22. A writable and computer-readable medium encoded with a program comprising:
-
searching for a first route from a starting point or a present position to a destination or neighborhood thereof based upon memorized map information; obtaining locus data related to at least one road or intersection learned, by detection of present position, in previous travel through said at least one road or intersection; searching for a second route near the first route based upon the locus data; and displaying said first and second routes with roads used in the searching distinguished from roads not used in the searching.
