Google wowed the world of navigation last October with Google Maps Navigation, available for free, initially on the Motorola Droid, retailing at $199.99, and then the rest of the smartphones powered by Android. Nokia has stepped in with Ovi Maps, bettering Google’s application by providing turn by turn direction for worldwide locations that are voice enabled and free –in contrast with Google’s application, which only works in America. While the Nokia Ovi Maps has a somewhat confusing interface, it performs well, and functions easily; this is the only navigation device you will need. This fact alone would sway most people considering the purchase of a Nokia smartphone that is unlocked, but beware some unusual limitations, UI related.
