30.5 Garmin Database Updates
The GDU 4XX MFD database updates can be obtained by visiting the flyGarmin® website
(flyGarmin.com). The flyGarmin website requires entering the System ID to update databases. This allows
the databases to be encrypted with the G3X system’s unique System ID when copied to the SD Card. The
System ID is displayed on the Database Information Page in normal mode, and on the System Information
Page in configuration mode. The Unit ID is different for each LRU in the G3X system, and cannot be used
for this purpose.
Since these databases are stored internally in each GDU, each GDU will need to be updated separately. The
SD card may be removed from the applicable GDU after installing the database(s). After the databases
have been updated, check the appropriate databases are initialized and displayed on the start-up screen
during start.
NOTE
Perform database updates on the ground only, and remain on the ground while a database
update is in progress.
NOTE
A single database update purchased from flyGarmin will allow all displays in the G3X
system with matching System ID to be updated, therefore a database purchase is not
required for each display.
30.5.1 Updating Garmin Databases
Equipment required to perform the update is as follows:
• Windows-compatible PC computer (Windows 2000 or XP recommended)
• SanDisk SD Card Reader, P/Ns SDDR-93 or SDDR-99 or equivalent card reader
• Updated database obtained from the flyGarmin website
• SD or SDHC card up to 32 GB can be used, 8 GB recommended for GDU 4XX units (Garmin
recommends SanDisk® brand).
• SDXC and SDUC cards are not supported.
NOTE
In the event there is a file corruption problem with the SD card, it may be necessary to
reformat the card. This can cause an issue when formatting the SD card using Mac OS,
where the newly formatted card will not be recognized by the avionics system. When using
a Macintosh computer to format the SD card, Garmin recommends using the SD Memory
Card Formatter application available as a download from SDcard.org. When running the
application, use the Quick Format option.
After the data has been copied to the SD card, perform the following steps:
1. Insert the SD card in the card slot of the GDU 4XX to be updated.
2. Turn on the GDU 4XX to be updated.
NOTE
Steps 1 and 2 can be performed in reverse order.
