I just ordered one and I live in VERY HOT climate, average summer time weather is 110. A few days ago, I left a level on my dash. When I came back from my errands, my level looked more like a bumpy boomerang! I will admit it was a cheap little one, but the plastic warped like a wide "U" and the magnet even was bent from the heat, and that is not a very comforting image if it happens to be expensive electonics. Anywho, I was wondering if Garmin's GPS 20x is safe on the dash or should I place it somewhere a bit more outta exposure? I'd rather have it inside my truck for ease and convience. If anyone knows I would appreciate any input! Thanks!
