Hey there. I recently purchased an etrex 20. It works quite well but one issue I have is there doesn't seem to be a way of turning the screen off, only changing the back light or turning the entire device off. Anyone know of a work around for either locking the controls, or the screen, so I don't accidentally press buttons when it's in my pocket and I can save some battery on a long hall? I'm using it for backwoods navigating if that matters at all.
