    About 1 in 3 rides not updloading from Garmin to Strava - bad time data messages.

    I have tried using the online resource to fix fit files to no avail.

    How can I stop this happening in future?

  • Could be a problem with the gmaptz.img file, i.e. the time map.
    First try using the webupdater to see if it offers you a time zone map update if it does then take it.
    If it does not then mount the Edge to the computer and delete the following file
    Garmin\gmaptz.img (This is the time zone map)
    Run the Webupdater after deleting the file and it will reinstall the map for you.

  • Cheers

    Have followed your instructions, fingers crossed it'll solve the issue.

    Much appreciated

  • I gave that a go, but todays ride is dated 2019 and using the fit tool online has not managed to fix the corrupted time data.

    What now?

    Can I save my profiles and then do a hard reset? Any guidance on how to do this would be hugely appreciated.
