Nokia Maps 3.09 - How can I change the language of the Map data? e.g. street names

The language used in the Map data is dependent on the language of the mobile device. If, for example, it was required to have street names in Mandarin, the device language would need to be changed to Mandarin.

Once the language is changed, re-download the map data to the device. This will ensure that the correct map data is downloaded.
