I see version 6.40 of the G5 software was released on December 18, superceding version 6.20, which I have. So, a question: What are G5 owners doing about software updates? Obviously, it's easy enough for an owner to accomplish without assistance, and I suppose it requires a logbook entry, but what if anything is required to complete the update legally? It would seem to be overkill to require this to be done at an avionics shop, despite Garmin's protestations otherwise on their software download site. (This is akin to paying a dealer maintenance facility to reprogram your automobile TPMs. Which, BTW, can be WAY more complicated.) Does the FAA even care?
