System Software and Configuration Load
System Power Up
Apply power to the G1000 system by connecting external power to the aircraft to energize
the aircraft and avionics electrical busses.
DO NOT RELY ON THE AIRCRAFT BATTERY TO LOAD SOFTWARE. DO NOT USE A
BATTERY CHARGER AS AN EXTERNAL POWER SOURCE DUE TO ELECTRICAL
NOISE IT MAY INJECT IN THE G1000 SYSTEM.
Power loss during a software upgrade may cause a LRU to become corrupted and
unresponsive requiring replacement. Remove power only when told to do so in the
procedure.
MFD & PFD Software Load
1. Open the MFD, PFD 1 (PRI), PFD 1 (SEC), and PFD 2 circuit breakers.
2. Remove Garmin database cards from bottom slots of PFD1, MFD, and PFD2 if present.
3. Insert the software loader card into PFD2 top card slot.
4. Turn on Avionics electrical busses.
5. Close the PFD2 circuit breaker.
6. When the “DO YOU WANT TO UPDATE SYSTEM FILES?” prompt appears, press the
YES
softkey.

SPLASH SCREEN?” prompt may appear. If it does, press the
NO
softkey. The splash
screen will be loaded later in this procedure.
8. When complete, the PFD2 starts in configuration mode displaying the “System Status”
page. Open PFD2 circuit breaker.
9. Remove the loader card from PFD2 and insert it into the top card slot on the MFD.
10. Repeat Steps 5 through 8 for the MFD using the MFD circuit breaker. The MFD does not

from the MFD and insert it into the PFD1 top card slot.
