Hello,
my 945 stopped answer so I restarted it (15 seconds Light button) and now I have there only starting screen (Garmin logo).
I tried some reset buttons like:
Start button + Back button, after first beep I released Start button after second beep I released Back button. But nothing still Garmin text logo.
I tried full charge it (or I tried discharge it) then connect to computer but Garmin Express or Software Updater did not find it. So after connect to MAC wath not found.
So I'm still on starting screen. When I push Down button I see some system info: http://bit.ly/2NWG7JV but that's only view what I'm able to see.
Please do you have some tip how to somehow reset it to factory setting or what to do (some secret button combination). I have my Garmin only one month.
I do not use any downloaded widgets, apps, only one popular watch face.
