I seem to be having trouble with the Google navigation. I can't seem to get a my location correct. I've tried it in many areas and it seems to be off by a couple of blocks. Keep in mind I live in NY so there shouldn't be any signal problems. I have GPS and WIFI turned on and still can't get great signaling for the GPS. This is a problem because I can't get turn by turn directions. Any one know how I can fix this?
