Since my GB update, the only problems I have noticed is a little more battery usage and the phone restarting itself when I try to turn it off. Now tonight when using my GPS navigation to get to a restaurant a few towns away, the vocal directions were correct, but halfway through the trip the Map stopped updating where the car was on the road. It's like the map just froze in one place. Still talked to me saying the directions to follow, but nothing moved on the map itself. I've used the GPS a couple times before while on GB and nothing like this ever happened. I'm hoping this is a one time thing, will have to check it tomorrow and see if it repeats this. Oh and I don't know if this matters or not, it was in my hand not in the Car dock I usually use in my car. Anyone have this problem before with their GPS Navigation?
