I had mine under shade in the cockpit on a 95 deg day, but with a
closed canopy. It worked just fine, but I actually melted/distorted
the RJ phone jack power connector! I forget what the Tg of ABS
plastic is, but I exceded it. Anyone else have this problem? I
managed to sand down the polycarbonate connector so it would fit, but
I may have to send the unit in for repair.
