Changing navigation sources:
1) Press the CDI Softkey to change from GPS to VOR1 or LOC1. This places the light blue tuning box over the
NAV1 standby frequency in the upper left corner of the PFD.
2) Press the CDI Softkey again to change from VOR1 or LOC1 to VOR2 or LOC2. This places the light blue tuning
box over the NAV2 standby frequency.
3) Press the CDI Softkey a third time to return to GPS.
NOTE
: KAP 140 equipped aircraft only: Each time the CDI Softkey is pressed or the navigation source
changes, a message appears (“NAV Source Changed – Select Desired Autopilot Mode”), regardless of

GPS steering guidance is still provided after the CDI automatically switches to LOC until LOC capture, up
to the Final Approach Fix (FAF) for an ILS approach, or until GPS information becomes invalid. Activating
a Vector-to-Final (VTF; see the Flight Management Section) also causes the CDI to switch to LOC navigation
source; GPS steering guidance is not provided after this switch.
