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…
As I wrote before the alerts come with the track, but be aware that when you directly copy .gpx files from a PC to the watch, they are lost. Fit or GC are the options that work. It worked the same way…
@bluefish - According to a recent response from Garmin, BaseCamp is still meant to serve their handheld devices. Thus, it is not deprecated... yet.
However, mass storage mode is definitely gone on all newer watches that have music support and/or Garmin Pay built in.
So You are basically right, but the correct wording would be that the watches are "no longer designed" to work with BaseCamp and vice versa, and Garmin does not support this combination. The Garmin connect web portal and the Garmin Explore App are recommended to be used instead. This is not satisfying as both of them need an online connection, which BaseCamp does not.
Workarounds are possible by using either Windows (reports say that BC on Windows has no issues) or, on macOS, using special drivers that emulate a mass storage device with MTP. I have seen such drivers on the web but refrained from penetrating my system with them. Garmin recommends Android File Transfer for accessing files and folders via macOS Finder. So this could help uploading custom maps at least, but does not emulate mass storage mode which is a requirement for BaseCamp.
The real solution would be if Garmin would decide to either make mass storage mode again available with a future firmware update (unlikely) or, alternatively, upgrade BaseCamp for macOS so that it supports MTP mode in the same way Garmin Express does.
Thank you for the correction. Correct as far as it goes.
Here also from my side a small correction :

The Explore app also works OFFLINE. You can download the maps you need at home via wifi, and then work completely without internet or mobile network. The only thing that is needed is a Bluetooth connection between the watch and the phone / tablet.
Explore is the only app that can work completely offline.
