A trail, or plot trail, is a string of position points plotted by the Global-

Map as you travel. It's a travel history, a record of the path you have 

taken. Trails are useful for repeating a journey along the same track. 

They are particularly handy when you are trying to retrace your trip 

and go back the way you came. On the screen, trails are represented by 

a solid line extending from the back of the current position arrow. 
The GlobalMap is set at the factory to automatically create and record 

a trail while the unit is turned on. The unit will continue recording the 

trail until the length reaches the maximum trail point setting (default 

is 2,000, but the unit can record trails 9,999 points long). When the 

point limit is reached, the unit begins recording the trail over itself.  
By default, the trail flashes once a second, making it easier to see against 

the background map. With the default auto setting, the GlobalMap cre-

ates a trail by placing a dot (trail point) on the screen every time you 

change directions (The trail update rate and the methods used for creating 
a trail can be adjusted or even turned off. See Sec. 5 for Trail Options.). 
To preserve a trail from point A to point B, you must "turn off" the trail 
by making it inactive before heading to point C or even back to point A. 
When the current trail is inactive, the GlobalMap automatically begins 

recording a new trail.
