GPS woes
I have a GTN 650 and GNS430W both installed by the same major avionics outfit. Although I have never had any previous issues with the 430 in the three years prior to joining it with the 650, both units have failed navigating at exactly the same time. It has happened about three times and in different locations. The error message I get on the 650 refers to ariel grounding if I remember correctly. I don't think it can be loss of signal as neither box went into dead reckoning mode and my handheld Garmin worked fine.
Has anyone had similar issues with their panel mounted GPS?
