Nokia maps & Directions is now a free to use service on Nokia handsets, previously the maps were free but you were charged if you wanted to use the service as a sat nav with directions.
All this is now free, worldwide.
Compatible devices: Nokia X6, Nokia N97 mini, E72, E55, E52, Nokia 6730 classic, Nokia 6710 Navigator, Nokia 5800 Xpressmusic, Nokia 5800 Navigation Edition, Nokia 5230. May work on others too.
Heres the direct link for the maps:http://www.nokia.co.uk/apps-and-services/ovi-maps
As I understand it the system works by downloading the required maps to your handset when you need them so you will get charged by your operator for data but if you have an unlimited internet bundle this will also be free.
