NOTE
When the CDI navigation source is selected to a GPS
receiver and the Auto Course is enabled in the Menu,
the course is set automatically by the GPS and is not
pilot-adjustable (see Section 4.4.6). This state is
indicated by the CRS field and Knob label shown in
green with an inverse "A". In this case, pressing the Left
Knob will enable you to set only the Airspeed Bug (IAS).
