Up until the recent update, Mapquest was the better nav app on iPhone. It is still better at keeping up with real time distances and direction, but you used to be able to silence the voice guidance easily. Now I have yet to find the button to disable that annoying bitch voice, as it nags rather than guides. Within 50 yards of a turn you get 3 or more voice prompts for the same direction. What was once the best nav app is not worth the trouble.
