Field appears in magenta

2.2.2. Navigation Source Select Buttons
The center button on the bottom of the display (
Figure 2-6
) allow the pilot to select
the navigation source for the CDI (
see
Section 4.4.5. CDI Navigation Source
for more
detailed information).
The CDI Nav Source Select Button is the center button (
Figure 2-6
). It selects which
of the available navigation sources will couple to the CDI, which in turn couples to
the autopilot (if available). Each press of the CDI Nav Source Button selects the next
available nav source, cycling through all available sources in a round-robin sequence.
The currently coupled CDI nav source is displayed directly above the CDI Nav Source
Select Button.
The available navigation sources are configured when the EFI was installed (depending
on what is installed in the aircraft and connected to the EFI). The available navigation
source choices are: GPS1and VLOC1.
