My Garmin Edge Explore is currently on firmware version 4.1 and I've tried to update it to 5.3 several times. Even after resetting everything, it won't install. Garmin Express is on the latest version and everything looks good, but when the device asks if I would like to install 5.3 and I clikck on "Install now", it shuts down and doesn't perform the update. After each restart it asks again if I'd like to install the latest version.
Any clue what the issue might be in this case? Thanks
