Dear all,
I have connected my FR 645M with USB to Garmin Express last week to check for the updates. However, it showed me there were 4 new updates released. One of the update is the new firmware version 6.20. When I clicked the "Install all", after a while, it showed me that "There was an error installing the update on Forerunner 645M".
I have power off the Garmin watch and computer and restart it. Also, I have checked the Garmin Express is updated to latest version. But still have the same error while installing.
Can anyone tell me what can I do? Can I manually install 6.20 into the FR 645M.
Currently the firmware version of FR 645M is 5.90.
Many thanks.
