Similarly, as illustrated in FIG. 22A, in addition to the symbol image 37′ indicating the scheduled travel course, symbol images 72′, 73′, 74′ respectively indicating a planned parking/stopping space, a travel course for parking/stopping, and a stop line mark for parking/stopping are displayed as well at the second display device 4 as being matched with the position of the road shoulder 71′ in the taken scenery 39. The symbol image 72 indicating the planned parking/stopping space may be displayed as an outline box shape. Here, to be easily recognizable on the screen of the monitor device 24 that is relatively small, the entire planned parking/stopping space may be lighted or blinked.
