Fix

When route navigation is executed, the first waypoint is the starting point position and the second waypoint is the waypoint. Also, at the time of changing the waypoint, the point where the waypoint is the starting point is the starting point position, and the waypoint after switching is the waypoint.

When the changeover condition of waypoint A is satisfied, waypoint B switches to the waypoint position. In the fix mode, the position of the waypoint A changes to the starting position. Also, the course line that passed through will remain on the map as it is. Keep the before state after passing through the final waypoint.
