发明名称 NAVIGATION APPARATUS AND NAVIGATION METHOD
摘要 A navigation apparatus includes map data, a control unit that searches for a route over which a vehicle is to be directed, using the map data, and a display unit that displays an arrow indicating a right turn or a left turn of the vehicle when the vehicle approaches a guide point where the vehicle is directed to turn right or left. The control unit determines the type of a first road which is connected to the guide point and which will be entered after the vehicle turns right or left at the guide point, using the map data. If the first road is a first type of road, the control unit causes the display unit to display the arrow in a first color. If the first road is a second type of road, the control unit causes the display unit to display the arrow in a second color that differs from the first color.
