I can run anything on it. iOS still a closed system - but that applies to apps, not data. Garmin is restricting data. On an iPad, I can open Microsoft XL files for example. I would not expect Garmin to allow other apps or OSs to run on their hardware (no one else does either). But restricting access to data is quite a bit further. What if Apple said on the iOS you can only access Numbers and Pages files, no MS XL files? Do you think they would enjoy the leading position they have currently? Right now if you buy a Garmin plotter you better be happy with their proprietary charts, because that is all you are going to see on them. Yeah it's their business decision to make. Hope it works well for them. Kansas City is a long ways from the ocean!
