A trail, or plot trail, is a string of position points plotted by the unit 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 unit 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, this unit creates a 

trail by placing a dot (trail point) on the screen every time you change di-

rections. (The methods used for creating a trail and the trail update rate 
can both be adjusted or even turned off. See Sec. 8 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 set inactive, the unit automatically  begins 

recording a new trail.
