Yesterday I met my cycling buddies at a park, then on my 1040 I selected a Course, then chose to Navigate to start, a distance about 1.5 miles away. The 1040 did navigate me to the start of the course, but then it acted like the course had ended and provided no turn-by-turn directions.
My work around was to simply reload the Course a second time.
Did this happen because the initial Navigate to start also happened to track the end of the route?
