3.5.1 Chart card overview
Your system reads FURUNO and NavCharts (NAVIONICS) charts, or C-MAP
charts, depending on its specification.
When you insert a suitable chart card in the slot and your boat is near any chart
graphic data, a chart appears. If a wrong card is inserted or a wrong chart scale
is selected, land masses will appear hollow. Insert the proper card and select a
suitable chart scale. Chart icons appear at the top of the display to help you
select a suitable chart scale. The table below shows the chart icons and their
meanings.
