I ran into this same problem yesterday with my N800, with my Wayfinder Navigator license--no voices with the maps I downloaded. I found the answer not on Wayfinder's website, but in this thread. It solved my problem perfectly. By going to Settings in the Dropdown menu on the opening screen of Maps, you can refresh your voices list, and then just select the ones you would like to download individually and try. Thanks again for the instructions. You would think that Wayfinder would have had this on their faq page!
