Map Orientation; Zooming In And Out Of The Map - Garmin GPSMAP 378 Owner's Manual

Map Orientation

There are three map orientation options: North Up orients the map
like a paper map. Track Up orients the map in the direction of travel.
Course Up orients the map so the direction of navigation is always
up. When using Track Up or Course Up, the North arrow indicates
the orientation. To change the map orientation, press MENU to open
the Map Page. Press MENU again. Select Set Up Map and press
ENTER. See page
43 for information.

Zooming In and Out of the Map

The map display has 28 available zoom scales ranging from 20 ft
to 800 nm (20 ft to 800 mi or 5 m to 1200 km). The map scale is
controlled by the IN and OUT keys, with the current scale shown at
the bottom right of the data window.
NOTE: The scale value represents the distance from one end of
the scale bar ( ) to the other.
To select a map scale (zoom in and out):
Press the OUT key to zoom out; press the IN key to zoom in.
Both the GPSMAP 378/478 have a built-in worldwide land database.
The GPSMAP 378 contains detailed maps of the U.S inland lakes
and the GPSMAP 478 contains built-in BlueChart g2 charts. The
GPSMAP 378/478 shows cartography as long as chart information is
available for the zoom scale you selected.
Map coverage conforms to the following conditions:
• Cartography is shown when the selected zoom scale is
covered by either the internal basemap or other MapSource
data loaded onto a data card.
• When the selected zoom scale is covered by both the internal
database and data card map information, the cartography with
the best resolution appears.
