Hm, with the vivoki of my wife, it sometimes takes 2-3 attempts to connect, but I did not see yet this error message. And since the Vivoki has no USB interface, I cannot advise you to download and fix the file. The best may be contacting Garmin Support directly. You could also try resetting the device - I see it has some small slit on one side - I do not want to mess with the one of my wife, not to erase her data, but it could be perhaps a reset button, so you could try pressing it. If it is not, you could also try removing the battery for a while. You better remove it for at least some 10 minutes, to avod there is a capacitor holding the charge for shorter periods. If nothing of it helps, have it replaced by the retailer.
Thank you. I tried everything, removing the battery, removed and reinstalled the app, cleared data, cleared cache, with no success. Finally called support late yesterday and they have tried everything else. The final solution is they are sending me a replacement. Thank you for your time on trying to help though. Really appreciate it.
