Wolfgang, sorry to hear of your problems. This isn't apples to apples but my
'Pictoral Pilot' and 'Altrak' [installed in a LNC2]work flawlessly and I
wouldn't part with them for any amount of money.. I say often that the Altrak
was the best investment [besides a new 0-320 Lyc] I've made in the airplane.
