Installation Instructions

Download the compressed update file onto your hard drive and extract it (.zip format).
Insert a FAT32-formatted micro SD card with at least 20 MB of free space into your card reader.
Copy the ''Garmin'' folder to the top level (root directory) of the SD card.
Safely eject the SD card.
Apply power to your G5 Electronic Flight Instrument.
Insert the SD card containing the software update. You will be prompted to confirm before the update is installed.
During the software update, the G5 will indicate ''Loading''. Do not remove power during the update process.
When the update is completed, the G5 will reset itself and turn on normally.
Repeat steps 6-8 for each G5 unit in the aircraft.
