Last Sunday after I had my $100 Hamburger, I went back in the plane and taxied to the run-up area. During that time the 430W had a "Kernel error", screen all black with the words in yellow. Turned unit off and back on and it was fine. Theory: It was noon in Texas and I do not have a windshield cover, the unit may have gotten to hot. Anyone else have experience with such a failure?
