I've heard a few times from my local support that I should use a cable for my watch software update. They know there is WIFI but better use a cable.
Yesterday and today I tried to update Enduro 2 to 19.34 version and it hanged at 52 or 54% with the message "Software synchronization failed" (I translated from polish message). I read that 19.34 was fully released. I used option which I found in Garmin Connect.
So, we can update using WIFI or not?? Of course this is much more convenient than connecting the watch to the computer via a cable.
