Hi all, I'm having difficulties since the update of google maps on my Samsung Galaxy S3. Before the update all was fine but since whenever I try to use the directions feature it doesn't follow the route like a normal sat nav. The directional blue arrow just points up and doesn't move around the route. The route indications in the top left corner are fine e.g. roundabout icons etc. The voice works fine. I have tried uninstalling and reinstalling but the same happens. Any ideas?
