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 (ESS BUS) and PFD (AVN BUS 1) circuit breakers.
2. Remove Garmin SD/MMC/FS510 cards from bottom slots of PFD and MFD if present.
3. Insert the software loader card into the MFD top card slot.

ENT key, then 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.
9. When complete, the MFD starts in configuration mode displaying the "System Status"
page.
10. Open MFD circuit breaker, remove the loader card from the MFD and insert it into the
