The GPSMAP 182/182C’s system has a built-in worldwide
database to 20 mi, with more detailed coverage available through
the use of the BlueChart or MapSource data. The GPSMAP
182/182C displays cartography as long as there is chart information
available for the range you have selected. Map coverage conforms
to the following conditions:
• When the selected zoom range is covered by the internal
database, BlueChart, or MapSource data, cartography is
displayed.
• When the selected zoom range is covered by both
the internal database and BlueChart/MapSource data,
cartography is displayed using the data with the best
resolution.
• When the selected zoom range exceeds the resolution of the
data in use, an Overzoom warning appears below the scale.
