Tried to upload ride from 510 but get message upload fails. Turned everything off & restarted. Sync failed message in garmin connect? Still cant upload a ride. Deleted some rides from 510 to make space no different.

If you have a Windows computer (different process for Mac), connect your 510 via the Garmin USB cable to your computer then in file explorer the mapped drive will typically be "D:\GARMIN." Your activities should be in the folder "D:\GARMIN\ACTIVITY." Look for the problematic .fit file. You should be able to locate the file based on the date. Then drag and drop the file onto this page - Import Data

After upload is attempted you should see either the message We don't support the file type you tried to import or Import Complete

If it fails, zip the fit file and attach it to this thread. We might be able to fix it.
