SECURE DIGITAL (SD) CARDS
Software files are uploaded into the G1000 using a Secure Digital (SD) Data Card. The card
contains all necessary files to load software and configuration settings to all G1000 LRUs.
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 (refer to Section 7).
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 a specific G1000 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 G1000 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.
NOTE
Ensure that the G1000 system is powered off before inserting the SD card.
The GDU data card slots use the Secure Digital (SD) cards and are located on the top right
portion of the display bezels (Figure 4-3). 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.
To install an SD card:
Insert the SD card in the SD card slot, pushing the card in until the spring latch engages. The
front of the card should remain flush with the face of the display bezel.
To remove an SD card:
Gently press on the SD card to release the spring latch and eject the card.
