Secure Digital Cards
The PFD and MFD data card slots use Secure Digital (SD) cards and are located on the
top right portion of the display bezels. Each display bezel is equipped with two SD card
slots. SD cards are used for aviation database and system software updates as well as
terrain database storage. The cards contain all necessary files to load software and
configuration settings to all G1000H LRUs. Not all SD cards are compatible with the
G1000H. Only Sandisk cards are approved for use with the G1000H. Use only SD cards
supplied by Enstrom. Basically, all software and configuration parameters are pre-
determined by Garmin and/or the OEM. During removal and replacement of LRUs,
software and configuration files may need to be reloaded.
It is very important that the technician use the correct card part number because each
card part number defines all files found on the card for this specific G1000H installation
except for certain configuration settings such as the aircraft registration number (N#) which
must be entered manually.
Use care when using the card during maintenance. The G1000H is designed to
immediately initialize the card upon power-up. On-screen prompts must be given careful
attention in order to avoid potential loss of data. Always read and thoroughly understand
all related information before attempting to use the card.
Install an SD card:
Ensure that the G1000H system is powered off.
Insert the SD card in
the SD card slot with the label facing to the left, pushing the card in until the spring latch
engages. The front of the card should remain flush with the face of the display bezel.
