I have discovered a bug in the Navigation app. When I load a route in Navigation, it shows a black line to lead me from where I am now to the first waypoint. That’s very helpful, but when I elect to turn off “Navigate via Start” under “Edit route settings” it often loses all the waypoints except one but still doesn’t remove the black line representing the route to the start. I'm still not sure why but sometimes it doesn’t happen.

Please ignore last message. I understand now what the black line is doing. It intersects the plotted route at the closest point. Perhaps it could be a bit more more transparent?
