I have had quite a few problems with the stock gps. Im not sure if its the program or the gps in the phone. I downloaded the "aura" app for navigation and it worked just didn't like the OS of it. But with that app you have to download the maps so it basically only relies on the phone for the gps signal for location not for the maps. I was wondering if anyone has tried any other navigation apps and if they work better than the stock version?
