I think it would be very useful if it was possible to upload from BaseCamp to Garmin Connect.
I know it is possible to export as a GPX or TCX file, then do a manual upload on Garmin Connect, but it would be a lot quicker and easier if you could upload directly.
Seeing as Basecamp already has features to sign-in to a Garmin account. This would be much more useful for me than the existing 'cloud storage' feature.
