How to reset iOS Maps data Whenever I use maps to get directions to any destination, Maps notes that I have to go over a toll road (denoted with a small € symbol). Except: I live in the Netherlands and we have no toll roads.
Absolutely no road I take should be a toll road, but Maps thinks they are. It even helps by saying "Toll required".

Is there a way to reset my Maps data?

I've had this problem on an iOS 9 iPhone 4S, and I've restored a backup from that device to an iOS 10 iPhone 6s, both show the same toll roads. Every highway or fast lane route is denoted as a toll road.

Possibly related, while navigating, iOS will commonly add extra names to the proncuation.
So for instance "Karel de Groote laan" is pronounced "Karel de-yipiyajeej-laan". Whenever it mispronounces a street name, it always add "yipiyajeej"

I don't think that's a problem with your iOS as much as it is Apple's map data, unless of course this issue doesn't happen with other iDevices. The best way to correct an issue with Apple's map data however, is to click on the information button in the maps app, then click on "Report an Issue" and you can explain the issue there so Apple can fix it in future iOS releases.
