I used to have those rain deflectors in my old truck but never installed the when I got a new one. One of my rain reflectors got damaged and it was so hard to remove that I didn't want to mess with anything like that again. Anyway, when it gets really hot out I crack the windows too and sometimes open the rear window sliding panel.
You're right, that's pretty hot! Somehow when
@murcod said "I leave them in parked cars" I was thinking inside temps and also not completely making the C to F conversion as well as I might have.
At least for me, the Mobius cams can take a licking and keep on ticking, so I don't worry about them too much at this point. I figure after having them in service this long they don't owe me anything even if something goes wrong and it would be cheap to buy a new case or even a new PCB if I ever need to. Actually, I thought I'd be using Mobius 2's by now anyway so but who knew the M2 would be such a lousy product. Good thing the Mobius holds up so well!
