Twice now I went to use my 67i and found it dead, about two weeks after I last used it and fully charged it. I normally store it in the Garmin soft case. So I started to wonder, did I turn it off, how long should a charge last with the device off? So yesterday I was playing with it for a bit and three times I noticed that when I turned it off, it powered back on about 10 seconds later. It was not in the case. It’s not something I can currently duplicate though it seems random. Has anyone else had this happen? V8.80 software, and I’m not sure if it did this previous to V8.80. There was a post about 3 years ago on a 66i doing this, but no posted cause or resolution.
