Navigate to a Point of Interest
For POIs that are in view on the map, you can easily use the Navigate
to Cursor command above; just use the cursor to select the POI.
The other method involves searching for POIs with the Find Waypoint
command, launched with the
WPT key. (See the searching example ear-
lier in this section, or turn to Sec. 6, Searching, for detailed instructions
on POI searches.)
After you have looked up an item with the Find Waypoint command,
use the

the screen, then press ENT . The GlobalMap 4000M begins showing
navigation information to the item.

Creating and Saving a Trail
A trail, or plot trail, is a string of position points plotted by the Global-
Map 4000M 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 repre-
sented by a solid line extending from the back of the current position
arrow.
The GlobalMap 4000M is set at the factory to automatically create and
record a trail while the unit is turned on. The unit will continue re-
cording the trail until the length reaches the maximum trail point set-
ting (default is 2,000, but the unit can record trails 9,999 points long).
When the point limit is reached, the GlobalMap 4000M begins record-
ing 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 4000M creates a trail by placing a dot (trail point) on the
screen every time you change directions. (The methods used for creat-
ing a trail and the trail update rate can both 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 set inactive, the GlobalMap 4000M automati-
cally creates and begins recording a new trail.
