The Map Page shows your present position and 

direction of movement as a triangular ‘Position Icon’, in 
the center of the map. The map display also shows the 
map scale and geographic details such as lakes, rivers, 
highways, and towns.

Use the  ZOOM IN and  OUT  buttons to change 

the map scale in order to show more map area with less 
detail or less map area with more detail. Press and hold 
to ZOOM the map scale rapidly. The map scale in the 
lower left hand side of the display is shown in  units of 
measurement selected in the ‘Units’ fi eld of the Unit Setup 
Page (not to be confused with the Map Setup Page). If 
you zoom in so far that the resolution of the map data 
is exceeded and the appearance of the map is no longer 
accurate, the word, “ overzoom” displays just below the 
map scale. 

In many instances the map displays an ‘ Accuracy 

Circle’ surrounding the ‘ Position Icon’. The eTrex Legend 
uses both map resolution and GPS accuracy in defi ning 
your location to a point within the circle. The smaller the 
circle, the more accurate your location. 

When using the ‘ Pan Map’ feature, a small outline 

 arrow (Map Pointer) can be moved about the page to 
highlight and identify map items or to scroll the map to 
view areas not shown on the display screen.

A Status Field at the top of the page provides satellite 

tracking and location accuracy information.

Two optional  Data  fi elds at the bottom of the page 

can be programmed to provide a variety of travel and 
navigation information. 

More detailed map features as well as information 

about those features can be downloaded to the unit from 
an optional GARMIN MapSource CD-ROM. When using 
MapSource data, the word ‘mapsource’ displays below the 
map scale whenever you zoom in to view map details.
