That one will, I'm certain, be no better than what's in there -- a cheap, consumer grade GPS receiver with no pedigree whatsoever. Little to no documentation, and no provision for an off-board antenna.
I should say up front, I have no dog in this fight -- I didn't buy the NavWorx box, I'm just an interested bystander with possibly a bit of experience making things work in ways the manufacturer may not have intended. I was thinking maybe if a guy could or remove or bypass the internal GPS receiver and wire in a known approved source -- like, say, the uAvionix or Dynon or a Garmin 430W for those lucky few -- MAYBE there might be some salvaging it. Now, that said, I don't know how much of the required "integrity" is GPS hardware/firmware, and how much is device firmware. In other words, I don't know whether swapping out the GPS for one that's on the "nice list" would be sufficient, or if it would also require firmware changes to the EXP unit as well.
As for ongoing firmware support or fixes, well, good luck with that. Unless someone buys NW's assets and decides to either expend substantial programmer and testing time on a dead product (not bloody likely) or release the source code (even less likely), I think what you have is what you got. After being bitten more than once, I have learned to never ever
buy anything based on promises of future upgrades or enhancements. If something doesn't work or isn't available when I buy, I assume it never will be.
