threshold to a small value
provides a quicker notification
when you are off course.
Tip: Direct to Next Waypoint
points the compass arrow
in the direction of the next
waypoint; this is the best
option when you are trying to

arrow to the highlighted route.
This is the best option when
you are trying to stay on the
route highlight.
