I got this problem that just seems to have surfaced within the past week. The first time I noticed, I started the car and the navigation showed my position about 12 miles away in the next town over. Now its been doing the same thing nearly every time I start up the navigation. I can correct it sometimes by going into settings/position on map and manually moving the cursor to my correct location. I say sometimes it works, because 50% of the time I can move the cursor to the position I'm at and it will then work just fine but other times the nav will have my heading completely wrong (I'm going north, but nav has me going south) and it will not correct. Sometimes it will just slowly drift off my real position and eventually it won't even be on a road anymore.
Tonight, no matter how many times I tried to correct the nav by moving the cursor, it kept my heading well off of where it should be, practically 180 degrees from the way I was actually going. So as soon as I started moving again the maps would be totally off.
Anyone ever experience this?
