Section

CDI page with TRN and TRK displayed.
CDI page with CTS and ETA displayed.
The CDI page will display the CDI in the lower left hand
corner of the screen if the unit has obtained a GPS position
AND there is an active waypoint. If the unit has not obtained a
position, but you have already performed a direct-to, it will dis-
play 'No gps posn'. If a position has been calculated, but there
is not an active waypoint, the unit will display 'No actv wpt'.
The CDI itself may be configured to your preference. The default is
for the CDI to deflect full scale at 5.0 nm (or mi, km) of cross
track error. See page 54 to set the CDI sensitivity.
