Aren't there some issues with Garmin cutting off people who bought direct from the USA, when it comes to upgrade pricing?
It isn't supposed to be possible to buy a new GNSx30 direct from the USA; nobody there (or here) is supposed to sell them without a bundled installation. But of course it is possible. Garmin try to stop it by not supporting such owners.
Honeywell also tried to stop it but have given up.
