The next step is to select the “Voices” tab at the top, we had been working in the “Maps” tab. Here, depending on the language you want, you will have an option to choose either a male or female voice to use for turn-by-turn navigation instructions. Once you have made your pick you may click on the “Download” Button at the far right and wait for the process to run it's course; again, you will need to respond to prompts on the phone as well.

Once that is done you may disconnect your phone and confirm your installation. In the GPS folder on your phone, launch the Application marked “Maps”. If everything went as planned you should now be looking at a map of the location where you are standing with a little red dot in the center of the screen. That's you!
To test the actual Navigation with Ovi Maps feature you will need to go to the “Options” menu and select “Search”. This will allow you to search by either an address or choose from popular destinations (those searched for frequently by other users) nearby.
Once a search is made, choosing the desired result of the search results opens an “Options” menu which has several items, one of which is of immediate interest to you. One must choose between “Walk to” and “Drive to.” These are quite self explanatory.
That's it: turn-by-turn voice navigation on your Nokia device (GPS-enabled, of course) through Ovi Maps, free. Happy Navigating!
