You can download an updater (at least for Windows) which downloads the whole head unit update data, which you then just copy to an SD card and stuff it into the reader in your car.
There is a similar service for Kia (they share head units with Hyundai - it's basically the same company)
I did a couple of successful updates on my Irish 2017 Cee'd .
Maps are updated every few months,
Kia claims to provide updates for cars up to 7 years old.
