2. Set the following menus to your preference:
Navionics:

Chart Overview
Select this menu to review the information about the installed Navionics chart card.
Turn on Easy View to simplify the Chart View. The icon size and text size increase for easier
viewing.
Turn on Dynamic Tides/Currents to display an icon on the Chart View that indicates the status
of the tides and currents. The provided data is affected by the station's time zone.
Select USA or International symbols to display on the Chart View.
Use Map Datum to change the map coordinate system used by the control head to match those
of a paper map. Almost all electronic charts use the WGS84 Map Datum and most likely do not
require a setting change. (Default = WGS84)
Use Chart Offset to move the chart position on-screen and correct a position error in the
cartography. Turn on Chart Offset, and use the sliders to adjust the latitude/longitude
coordinates. The Chart Offset setting applies to all charts, not just the chart that requires
correction.
Turn on Chart Boundaries to display chart boundaries on the Chart View. The dotted lines of a
chart boundary indicate an area that contains a different map. Use the Joystick to move the
cursor within a chart boundary, and press the +ZOOM key to see a closer view of the chart.
