I can only speculate, since I have seen no reports of the changes in this firmware version, that this is the major revision required to make the 4XXW/5XXW compliant with the 2020 ADS-B out precision position source requirements....
Steve or Matt, can you confirm and possibly fill us in on what has changed?
If this is that update, maybe it is the first of a wave of firmware upgrades that will get the GPS's and the xponders up to snuff for 2020?
