A thread relight: I had a problem last flights; the "press to accept" at start up would not respond at all to being pressed, so no useful navigation. The touch screen still works. 'cause I could touch the power button, which changed the display to brightness and sound, and I could touch to select those. And I know it's navigating inside, as when I landed at a buddy's grass runway, it gave me a terrain warning as I approached. But, for three flights, it would not press to accept, so no navigation.
Has anyone else had this trouble?
