USB Mass Storage not working

@bluefish - ok thanks for the clarification! I haven't tried the Garmin Explore App with a Bluetooth-only connection yet. If this app could transfer GPX tracks "on the go" to a fenix or other recent watch model, that would be a at least one great step ahead. An important precondition is, however, that the tracks would not be modified in any way during this transfer. Especially in the case the tracks are not in alignment with a map. I have seen such effects some time ago in the connect web portal, not sure if this issue is still happening. For some activities such as geocaching, mountain biking etc. the tracks must be transferred exactly as they are.

That's exactly how it works.

Another option is the CIQ-app Gimporter. If you send .fit files to your watch, you can also have exactly the turn-by-turn alerts you defined (e.g. with Locus Map on Android).

If you upload a track in Garmin Connect and then send it to the watch,  the track is not modified or matched to the maps. IOnly turn-by-turn alerts are added automatically, which works well, but not 100%.

It is important to use "follow course" and not "use map" in the routing settings of the watch. Otherwise the watch will match the track to the maps and will also recalculate routes during the activity

These methods both require an online connection.

Point 1: True, this was my answer to:

Point 2: Not true, this just requires a bluetooth connection to a phone with the corresponding app!

Are you sure ? Could you try this once ? Turn off the internet connection on the phone and see if it works. In the past it worked. But as far as I know, this has been disabled for some time.

Just found that :

and in the IQ Store :

Notes:

* Since 2019 the Garmin Connect App just refuses the connection from gimporter to gexporter, if the phone has no internet access (although none is needed).

„Please bug Garmin with reports about: "`makeWebRequest` not working to `localhost`, if the phone has no internet access."

All good :)
