2001 Cirrus SR-22 Dual Garmin 430 non waas. Sandel SN 3308 HSI, S-Tec 55 Autopilot.
Has anyone ever had this happen. Intermittently Nav1 will have complete loss of GPS signal. Nav2 has no issues during the same timeframe. Not transmitting, fuel pump, flaps or anything like that. Signal levels come and go randomly, sometimes for only a few seconds, sometimes for several minutes. Had this issue very intermittently last year, and then everything was fine until a few weeks ago.
Has anyone had this happen? And what did they have to do/replace to get it fixed?
