Me and my wife have IPhone 5s and maps work great, voice is perfect. A few days ago my Brother and Sister-n-law both got IPhone 5s and I can't get voice to work on either one in Apple maps. Siri works, sound works on every thing else just not maps. Sound is checked loud on all 4 phones in the map settings screen, all Verizon, all in VA. I finally gave up and told them I'd ask here and see what ideals are out there, nearest Apple store is 2.5 hours away so that's not an option. It's strange, we were all 4 sitting on a couch, typed in the exact same place and hit start, me and my wife's phone spoke the first directions and the other 2 just showed the directions on the screen???
