4.12.2.3 Downloading GIA and GSA Maintenance Logs
If additional assistance is needed troubleshooting autopilot faults, the Maintenance logs can be
downloaded to an SD card as a text file (.txt) and emailed to Garmin Aviation Product Support at
Avionics@Garmin.com. Please call Garmin Aviation Product Support before you send a Maintenance
Log to notify them you are sending it to prevent a delay in response. You may download multiple GIA
and GSA Maintenance Logs to the same file, however in your email to Garmin you must furnish the order
in which they were downloaded (i.e. GIA1, then GIA2, then SRVO PTCH MON, then SRVO PTCH
CTL, etc.).
1. Insert a FAT 32 formatted SD card into the top slot of the PFD before turning on the displays.
2. Power up PFD and MFD in the configuration mode.
