supplemental data card with a
terrain and obstacle database
present.

has not occurred.

If a mismatch has occurred, load
correct database/software files
or replace all the supplemental
database cards as a set.

received from the AUX – GPS
STATUS page.

If a non‐Garmin traffic device is
installed, refer to the
manufacturer's maintenance
manual to determine if it is
operating correctly.
•
Check GIA2/Traffic Device wiring
and connectors for faults.
