Has anyone upgraded to this version and if so, does navigation still work? I don't want to repeat the issues that i had with the upgrade to 12.60

I checked your procedure on my 820:
1.The running device is connected to the charger,
2.I turned it off with the button,
3.after charging to 100%, I disconnected the charger,
4. 820 started normally, touch and all buttons work normally
My firmware is 12.70
It looks like your case is isolated.
If I were you, I would reset the device to factory settings. If there are still problems, report the fault to Garmin (warranty?).
I had something similar happen on a firmware upgrade a year or so ago. It resolved after I left it alone for a couple of hours and it finished starting. I also had a map upgrade that took 2 hours to reboot.
