For fuel stops, I just leave my GPS on the bike unless it's a super busy station when I'll put it in a pocket. For lunch, I take the GPS in so I can look at maps of the surroundings to see what's up after lunch. Today I went to the city of Belfast on the other side of the Penobscot. I tossed my jacket over the GPS and went inside for half an hour. This is typical but sometimes I would toss it in a hard pannier. I have never used the "security screw" on my Montana 650. I recall several years ago, an inmate posted about someone vandalizing the screen on their GPS. IIRC, it was a soft screen and was cut. I suppose even Gorilla glass can be vandalized but may just take more effort.
