It's a non-fix if I have to do that every year (or every however-often-I-notice-an-error, the first error I noticed was within a year). Google Maps is constantly updated. Not to mention that Kia aren't going to be supplying updates in 10 years, while Google probably are (and if they aren't, I can still use Carplay and a different set of maps).

you said they bothered you, so I suggested a fix. no obligation to do it if you don't care.
