Dynon HDX; PFD position correct, VFR map not

Running a full Dynon 2020 compliant (in & out) set up with a 10" HDX. I use Seattle Avionics for the maps. Been flying for about a year without issues. Recently I have noticed at my home base airport that has a helicopter school on one side and the fixed wing on the other side of the traffic pattern, I will get 'traffic' warnings because the map will show me on the other side of the runway with the helicopters (upwind vs downwind type scenario). When landing, the PFD shows me right on the runway. I have even (intentionally) crossed the center line and the PFD shows this. I have reloaded software (Dynon & Seattle) and verified the correct nomenclature and GPS pin position in the setup menus, number satellites, etc.

Again, everything was spot on until about 2 months ago.

Any thoughts?

If you haven’t done so already, I recommend posting this on Dynon’s Skyview forum. DYNON usually responds within a few days to most posted questions.
