You need to have your location services on for mapquest. If you do ios6 you will get apple maps with turn by turn. But it doesent include mass transit directions or walking unlike google maps but it does include turn by turn.
I would be completely lost without my turn by turn navigation. It may be a small glitch with the developer of Map Quest.
I want to remind you and the community that we have our own VZ Navigator too! Check it out: http://bit.ly/SmnzQg
