Update Trail Criteria (Auto, Time, Distance)
The options are automatic, time, or distance. When it's in the default
automatic mode, the unit doesn't update the plot trail while you're
traveling in a straight line. Once you deviate from a straight line, the
unit "drops" a plot point (trail waypoint) onto the trail. This conserves
plot trail points. If a plot trail uses all of the available points allotted to
it, the beginning points are taken away and placed at the end of the trail.
