CDI (GTN 650 only)

The GTN 650's CDI key is used to select data that is sent from the GPS or
VLOC receiver to the external CDI (or HSI). CDI selection is available on the
Default Navigation page. When the external CDI (or HSI) is connected to the
GPS receiver, "GPS" is shown on the annunciation bar. When the external CDI
(or HSI) is being driven by the VLOC receiver, "VLOC" appears instead.
NOTE: The VLOC receiver must be selected for display on the external CDI/
HSI for approaches which are not approved for GPS. See the ILS example
in the Procedures section for more information.
NOTE: GPS phase of flight annunciations (LPV, ENR, etc.) are not applicable
to the external CDI (or HSI) when VLOC is active.
NOTE: The internal on-screen CDI information is based on GPS data and
cannot be used for primary navigation.
NOTE: If the unit is not configured for a CDI key, then the "activate GPS missed
approach" will only resume automatic waypoint sequencing. The user must
switch to GPS navigation, if desired, by using their external source selection
method (this is typical an EFIS system).
1. The navigation source is shown in the center of the annunciation
bar at the lower part of the display.
