How to clear Apple Maps cache or force map refresh

Hello,

I just noticed that Apple Maps now supports multi-language street names, these informations are taken from OpenStreetMap. This is great news for multi-language speaking areas, where the street names where available only in one language and if the phone was set to any other language, than the TTS would say a bunch of stupid, hard to understand street names.

I just noticed that in my city the street names now appear on Hungarian as well, the map updated on my iPad and Mac, but on my iPhone is still stuck, I guess after an update it will show as well.

Is there any way to force this update, by clearing the cached maps or by forcing to reload the map data?
