Finding your current position is as simple as turning the GlobalMap 

on. With an unobstructed view of the sky, the unit automatically 

searches for satellites and calculates its position in approximately one 

minute or less. 
If for some reason satellite acquisition takes longer, you may be inside 

a structure or vehicle or in terrain that is blocking signal reception. To 

correct this, be sure you are positioned so that the unit's antenna mod-

ule has as clear a view of the sky as possible, then turn the unit off and 

back on again. 

The map is presented from a bird's eye view perspective. The current 

zoom range shows in the lower right corner of the screen. 
1. Press the 

 key (zoom in) to move in closer and see more detail in a 

smaller geographic area. 
2. Press the 

 key (zoom out) to move farther away and see less de-

tail, but a larger geographic area. 
When you are traveling, the map will automatically move as you move. 

This keeps your current location roughly centered on the screen. 
You can manually pan or scroll the map northward, southward, east-

ward or westward by using the arrow keys, which launch the cross-hair 

map cursor. This allows you to look at map places other than your cur-

rent position. To clear the cursor, press 

, which jumps the map 

back to the current position or the last known position. 

Use the cursor to determine the distance from your current position 

(or last known position when working indoors) to any map object. 

Simply use the arrow keys to position the cursor over the object or 

landmark. The distance, measured in a straight line, appears in the 

pop-up box. Press 

 to clear the cursor.
