I think it is going to be a replacement/competitor for the IFR TSO'd navigators on the market. Likely the same capabilities.
I put a GNS430W in my panel in 2019 because two airports I fly into regularly about 667 nm away had only RNAV approaches and the nearest VOR or ILS was 90 miles away. I'd successfully avoided buying it for two decades mainly because of the very expensive subscription databases it consumes. To my surprise, my renewal this year is lower than last year, I think. But the vendor elected to change some parameters in the update manager to autolaunch its application on my main work computer. Vendor applications that tamper with my system settings without asking at upgrade time quickly find themselves locked in an operating system jail with no access to increased privilege settings.
Any company that thinks this is ok, gives me a very strong incentive to find an alternative, so, Dynon's announcement is very timely and I think it's safe to say I'm anxiously waiting to be an early adopter.
