I put "That site is for USA and Canada" in quotes, because that is what it says:- I investigated further, because it didn't feel like "The official Hyundai System & Map Update" site ...
MAPNSOFT.COM is registered with GODADDY, by someone who claims to be a private individual, who doesn't need to reveal their identity. It links to an actual registrant called "DomainsbyProxy.com", but that is just more obfuscation (it too belongs to a private individual).
The Privacy Policy for the website, makes reference to "Hyundai AutoEver Inc." - which is a real (Hyundai) company. The contact address they give (3545 howard way costa mesa ca 92626) appears to be actually
occupied by "Sovereign Lending Group Incorporated"
I seriously doubt they are authorised by Hyundai to sell maps, or that there is anything official about them
