HERE Maps - How can I change the language on the map in my Windows Phone 8?

The language used in the map depends on the language set in your phone. If, for example, you want street names to be displayed in Mandarin, the language of your phone would need to be changed to Mandarin.Go to your phone settings and tap language + region. Go to Browser & search language and choose the language you want. You may then need to download the map again.
