A user of my G5 gauges, Elliott in Canada, recently reported to me that the CDI on the G5 gauge was rapidly toggling between GPS and VLOC after the recent AAU1 (Aircraft & Avionics 1 or 1.30.12.0) update.
After further investigation, the issue is confirmed to be caused by the incompatibility between the Working Title Garmin GNS 430/530 addon and the Just Flight PA28 Arrow series — Arrow III, Turbo Arrow III and Tubro Arrow IV.
Other aircraft, default and 3rd party, so far tested, including the Just Flight PA28-161 Warrior II, are not affected.
Temporarily, users could uninstall the Working Title Garmin GNS 430/530 addon should they want to continue flying the Just Flight Arrows with the FIP gauges.
The bug is hope to be solved by either Just Flight or Working Title soon.
