Chart View
Chart View - This view shows cartography from the built-in UniMap™ or an
optional MMC map for the area surrounding your current position. The current
track (also known as the position history or breadcrumb trail) showing where the
boat has been, along with saved tracks, waypoints, and the current route (when
navigating), are overlaid on the chart. You can use the 4-WAY Cursor Control key
to shift/pan the chart to another area. You can use the ZOOM (+/-) keys to zoom
in and out. You can use the INFO key to get information on the chart objects
near the cursor.
