Plug-In Cards - NorthStar Multi-Function Unit M121 Installation And Operation Manual

1-3 Plug-in cards

The M121/M84 can use two kinds of C-MAP™
SD-Card plug-in cards:
1. Chart cards have chart details required for
navigating in a particular region. When
you insert a chart card, the extra details
automatically appear on the Chart window.
You can plug in up to two chart cards
at once. If the chart shows a region not
covered by a chart card, then it displays a
simplified built-in world chart.
2. User cards store navigation data. A user card
allows navigation data to be transferred
to another compatible instrument (see
section 15).
