Dual Garmin G5’s, GMA345 audiopanel, GTN650Xi COM/NAV/GPS and a GTX335 ADS-B out transponder. The existing Garmin GNS430 COM/NAV/GPS is kept as backup. Please note that the GNS430 has been around since 1998 and now 25 years later Garmin has announced that repair capabilities for all GNS series parts will be terminated during 2023. The same happened to the Garmin GMA340 audiopanel in 2022. So today when doing panel upgrades you must take into consideration that your existing avionics such as the GMA340 and GNS430 will no longer be repairable if it should fail. We have not heard anything about the GTX330 transponder but hopefully Garmin will have repair capabilities several more years as it was launched a few yeas later than the GNS/GMA.
