An autozoom feature is available which will automatically adjust from an en route scale
of 2000 through each lower scale, stopping at a scale of 1.0 as you approach your destina-
tion waypoint. The autozoom feature is turned on/off from the map setup page described
on page 36.
The map page also displays a background map showing lakes, rivers, coastlines,
highways, railways and towns. When a map scale is selected below the lower limit at
which the map detail was originally created, an “overzoom” indication will appear on the
map display, below the scale reading. “Overzoom” indicates that the detail at this scale
may not accurately represent actual conditions. If you continue to zoom in to lower scale
settings, “overzoom” will be replaced with “no map” and the geographic detail is removed
from the map display (but, the airport and navaid detail will remain).
The “Setup Map?” option (described on page 35) allows you to defi ne the maximum
scale at which each map feature will appear. This provides you with complete control to
minimize screen clutter. You can also quickly remove items from the map using the
c
key.
To quickly declutter the map display, press the c key momentarily (as often as
needed) to select the desired amount of map detail.
The right-hand side of the map page includes four user-selectable data fi elds. By de-
fault, the displayed data is: destination waypoint name (WPT), desired track (DTK), dis-
tance to destination waypoint (DIS) and ground speed (GS). Any of these data fi elds may
be changed to display a different data type, as outlined on page 37. You may also remove
the four data fi elds from the map to show a larger map image, as described on page 37.

The c key allows you to quickly declutter
the map display, providing four levels of map
detail. Note the “-1” and “-2” (“-3” is also
provided) suffix designations above, indicating
each successive declutter level.
