Update Trail Criteria
There are three options for updating trails: automatic, time or distance.
When it is in default mode (automatic), the unit does not update the
plot trail while you are traveling in a straight line. Once you deviate
from a straight line, the unit drops a plot point onto the trail. This con-
serves plot trail points. If a plot trail uses all of the available points al-
lotted to it, the beginning points are taken away and placed at the end of
the trail.

mile/nm/km if you update by distance. The default is 0.10 miles.
