VFR Settings
VFR settings for map layers are the same as factory settings
except for the following changes:
Custom Settings
The “Custom settings” preset item represents the most recent
map settings that have been modified by the pilot. Every time a
setting is changed manually, the custom settings are updated.
Selecting a different preset does not change the custom settings.
However, if a different preset is selected and then at least one
settings change is made, the custom settings will be updated to
reflect the complete set of new settings.
