While navigating, you can access playlists and listen to your music, audiobooks, and podcasts without going back and forth between applications. You can even place a phone call directly from search results. If you want live voice directions MotionX even comes with a full free 30 day Live Voice Guidance package. Courtesy of MotionX. After the first 30-days, you can purchase the Live Voice Guidance during the months you need it for $2.99 or purchase a full year for $24.99.

With MotionX-Routes™ technology, “the MotionX Smart Router calculates the best route, whether you are driving or walking.” The walking routes are designed specifically for pedestrians, so if you park your car several blocks away, it will “walk you” to your destination and back to your car.
