WARNING:
If you uncheck the Update Trail option, automatic trail

Update Trail Criteria
The options are automatic, time or distance. When it is in the default
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 onto the trail. This conserves plot trail points. If a plot trail
uses all the available points allotted to it, the beginning points are
taken away and placed at the end of the trail.

dialog box will appear, allowing you to input the desired update rate or
