Hello pdavid89 !

It seems you need to visit these links first https://support.google.com/maps/answer/63471 and https://developers.google.com/maps/documentation/javascript/localization . Our Google maps integration uses the bx_lang_name function which defines the current language from the settings user's browser and user's direct choice and then only from the default language settings. So you need to have the Hungarian language and mark it as the default on your site.
