Garmin G3X Touch flight data log — export & score every landing

1) Enable data logging

G3X Touch logging is off from the factory — turn it on once in Configuration Mode, a one-time button-hold. Already have a data_log folder on your card? Logging is on; skip to Step 2.

Enter Configuration Mode: with the display off, hold the MENU button on the bezel and apply power (master / avionics on). Keep holding until Configuration Mode appears, then release.

Then navigate — touch the screen or turn the Move Selector knob to move and select:

1. Open the Data Log Configuration page.
2. Set SD Card Data Logging to Enabled.
3. (Optional) on Max SD Card Log Files, press Clear to show - - - - — unlimited logs, so old flights aren't overwritten.
4. Exit, power off, then back on. It now writes one .csv per flight to data_log whenever a card is in the slot.

2) Insert your SD card and fly

1. Find the slot — the SD card slot in the bottom-center of the display bezel.
2. Insert a full-size SD card label-up until it clicks. Leave it in permanently.
3. Fly normally. Logging runs the whole flight on its own.

3) Offload and upload

1. Power off, then push the card in to eject it and pull it out.
2. Read it (below) and open the data_log folder — one .csv per flight.

Upload at landing.fyi →

Grab every log_*.csv file from the SD card and upload them all at once — landing.fyi scores each flight and quietly ignores any duplicates, so it's safe to select the lot.
