A vehicular navigation device includes a control circuit to designate a
route to a destination from a start point to be defined. When a route
designation instruction is inputted, it is determined whether an
intersection being a target for route designation is present close to the
current position. When the intersection being the target is present, it
is determined whether a lane the vehicle is traveling is a traffic
directed lane that includes a traffic direction. When the traveled lane
is determined to be the traffic directed lane, a start point is defined
as an exit of the intersection reached by following the traffic
direction. When the traveled lane is determined to be not the traffic
directed lane or when the intersection for the target is determined to be
not present, the start point is defined as the current position.
