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.
