Just a quick observation from my Gaspe/NB ride last week: I didn't have time to install the rugged mount, so simply carried the Montana in my Aquabox all week. The Montana touch screen began to scroll uncontrollably a couple of times when the sun shined directly into the Aquabox clear screen cover. So, it appears the screen scrolling issue is not just tied to placing the screen protector on the unit, but is a factor of the unit getting above a certain temp.
