This chapter shows you how to do the following:

2.1 Chart Type
A world map in raster chart format is included in your unit. A vector chart for the US
coastline (Alaska and Hawaii included) is provided also. To use this chart plotter as a
navigational aid, electronic charts (stored internally) for the area you navigate are re-
quired. Contact your dealer about charts for your area.
There are two types of charts available with this equipment.
[Raster]: Raster charts are digitized scans of NOAA paper charts. Raster charts have
information like notes, source diagrams, tidal diamonds, horizontal and vertical datum,
etc.
[HO]: HO charts are S-57 format vector charts (digital files) that contain marine fea-
tures and information created for marine navigation. These charts are made according
to the International Hydrographic Organization (IHO). HO charts are available from C-
MAP, Navionics, Mapmedia, and NOAA (National Oceanic and Atmospheric Admin-
istration).
How to select a chart type
1. Open the home screen, then select the [Chart Plotter] display.
2. Open the Layers menu.
3. Tap the chart type from among [Auto], [Raster] or [HOs].
*: [Auto] automatically switches the chart type according to chart availability and prior-
ity.
