Update Trail Criteria
There are three criteria by which trails may be updated: automatic,
time or distance. When it is in the default automatic mode, 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 (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.

   

Update Criteria with Time selected (left). With the setting above, the

trail would update every three seconds. Distance is selected (right). It

is set to update the trail every .10 of a mile.

Trail Update Rate

You can update a trail by time, with a range from 1 to 9999 seconds.
The default is 3 seconds. You can update by distance, with a range from
0.01 mile/nm/km to 9.99 mile/nm/km. The default is 0.10 mile.
