Hi, I have an iPhone 5 and a Nexus 7. Earlier this week I was driving to Atlanta and it appeared that Navigation was a few seconds slower on a number of occasions and sometimes was significantly slower then did a "String of voice directions" to catch up. (Like, TakeExit85BtoMariettaStayLeftMoveRightProceed8miles....." Has anyone else seen this? Google Maps on iOS were fine (had them both running, son's iPhone 5) at the same time to test the difference if any. Just thought it was strange. Happened enough to notice it, didn't cause a huge issue because when we hit Atlanta it was rush hour, (ugh) so I could have been hand delivered directions by Pony Express and it wouldn't have mattered!
