To enable the chart and navigation features, the control head must have a GPS Fix from an internal or external GPS receiver (see
Getting Started to check the sensor reception). Some of these features also require a compass/heading sensor to be connected
to the control head.
The selected chart source also influences the menu system. When you change the chart source, the menu options for the chart views
change, allowing you to add navigation data, shading, or alarms. See Select a Chart Source for details.
