I've setup my new etrex 30x on Garmin Express (and BaseCamp). I've matched the account with my Garmin Connect account. Nothing syncs automatically. In Connect I have to browse to my USB connected device and manually upload GPX files and edit their names when uploaded. Connect is synced with Strava but doesn't receive any of the activities. Connect shows 'Unknown device' for the manually imported .gpx activities and tells me I have 'no devices on Garmin Connect' and to use Express to transfer information.
I've left it on for hours and nothing transfers or syncs. The whole thing is pretty useless to me, any help?
