ABSTRACT:
A goal direction mark and a distance to a goal are indicated when the car has approached the end point of route. When the car has deviated from the guide route to the goal or is running backwards on the guide route in a direction that is opposite to the direction of the goal, there is indicated a mark to inform the direction of progress to the goal on the guide route. When the car has deviated from the guide route and the guide route is not indicated on the map picture, there is indicated the direction to the goal or the direction to the guide route itself. When the start point of route is remote from the present position at the start of the guidance, a mark is indicated to inform the direction to the start point of route. The driver is enabled to easily determine relying upon the indicated mark in which direction he should proceed. When the map picture is scrolled, there is informed the goal direction, route direction or the direction of progress to the goal on the route. The user therefore is enabled to easily know the direction to the goal.
