PURPOSE:To improve the operability of a navigation device in the navigation device provided with a route calculating function. CONSTITUTION:Route calculation is started after a map picture displaying a target place mark 22 as shown by C is displayed. Thus, such a matter that the route calculation based on an erroneous target place is executed, is prevented. While route-calculating, the display picture of D is displayed. In the display picture, the map is fixed and a vehicle mark 25 is moved according to the running of the vehicle. When the display map is fixed, a map memory is opened. When route calculating data is written in the opened map memory, the route calculation is executed without adding a memory and a map display as shown by D as well, is executed during that time. The route calculation is stopped on the way by a cancel switch 13e, etc. |
