what happened to the GPS? RAIM notification or did it go blank?
Also, what kind?

Don't hear about GPS failures often.

I is an AvMap with the Gold upgrade.
Have had my share of problems with this unit. Mostly it is with the up grade
card.
Then I had the unit go bad, another time the power cord had an internal short.
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.
It is back in the shop. Let's see what they diagnose the problem this time.
