It is already available to all users of the Nokia N97 Ovi Maps completely free for all over the world and for life. Already you can download Ovi Maps for the N97.
For users who need to update the maps, you must first have the software updated versión2.0.x. The new Ovi Maps is available through the software update client in the device. You simply open the Applications Folder, Software Update client (big green arrow) and choose the new Ovi Maps from the list.
