Does anyone know the current state of Garmin service on its GNS430W panel-mount? At one point it was around a grand to have your avioniker send it back to the factory for a complete O/H. Then I heard that they had stopped doing that for the non-WAAS units. Of course, mine has now developed avioniCOVID and probably needs the full treatment. I can't find out if Garmin is still doing it, and if so, how much it's gonna hurt.
