Set it up once
Turn on Garmin sync in the server settings and enter your Garmin Connect login.
Garmin Connect import
MTL Explorer can download your new Garmin Connect activities automatically. The files are saved on your own computer and appear on the map like any other track.
Turn on Garmin sync in the server settings and enter your Garmin Connect login.
Open Settings → Import & sync → Garmin and choose Sync now, or let it run on its schedule.
Activities you already have are not downloaded again.
New activities are imported and show up on the map and in your statistics.
The setup guide shows where to enter your login and which folders to connect.
Watch the download and import progress, then check for files that need review.
If downloading an activity times out, MTL Explorer tries again with the activity's original FIT file.
MTL Explorer remembers each Garmin activity, so later syncs skip it.
The retry usually helps with timeouts. It can't fix every error, and the second download can fail too.
Check Garmin command output in Settings → Import & sync. Tool status is in Settings → Maintenance → Advanced tools.
Downloaded activities work everywhere: filters, map, statistics, and segments.
A sync is skipped when Garmin sync is off, another sync is running, or files are still being imported. Check the reason shown and wait for the current work to finish.
Read the error and check your Garmin login in the server settings. Retrying won't fix a sign-in problem. Meanwhile, export activities by hand from Garmin Connect, and don't keep restarting a failing sync.
