The unit just goes blank with lots of yellow, blue and green lines. If I
do a "
Ram clear" the unit works fine again, but I would have lost all my flight
plans.

I had this happen to mine a couple of times. Although "clear starting it"
always solved the problem, the ultimate fix was a software upgrade that
AvMap did for free at OSH '04.

I'm surprised and disappointed to hear about the other problems. Ours has
been absolutely bullet-proof, and the unit seems to be built like a tank.
