Changing language of street names in Apple maps
How can I change my street names to French or English instead of Flemish?
iPad 2, iOS 6
The names of streets should show up in whatever languge is official or predominant for the locale (meaning if you look at a map of France, it will show street names in french). There is a Map Label setting in the Settings app for maps, but I don't beleive it will effect street names.
