So from the looks of it, these vendors copy genuine Navigation SD cards and sell them online. Or they deciphered the algorithm that creates the internal ID, and they copy the looks of the real card.
As you need to insert the card in the car first, I assume the car does the check to see if the card is genuine. The car does an offline check and approves the card.
And when you update, there are two possibilities:
1) If they copy genuine SD cards, you don't see any issues as long as you're the first one to update a card with that ID.
2) If they create their own "working" internal IDs, Mazda Toolbox doesn't compare the internal ID to a database containing all IDs when updating, so updates go through. Every now and then someone at Mazda or NNG does a manual check and flag the invalid serial numbers they can find.
Either way, it seems like not everyone gets these warning notices so it's a deterrent more than anything. However, I've heard stories of VINs getting locked out, but that would mean that the car does an online check when you install a new card. Perhaps it only locks the card, and only when you attempt to update the map. Confusing.
Mazda uses a white-label version of iGO for navigation, and I find that to be really funny as it shares so much in design with the iGO I had installed on my HP PDA back in 2008. NNG, the company behind the program, makes quite a lot of money from these navigation solutions. NNG has iGO for iOS devices and the North American map only costs $29.99 -- and it has free updates. I doubt it'll happen anytime soon, but they should switch to a modular map system where the infotainment updates parts of the map that need updating.
