Up until a few months ago my M3 navigation system provided accurate routes. Now, when navigating to my home (I know how to find it on my own), the navigation sends me around the neighborhood or sends me part way down a road and then suggests a u-turn in the middle of the road. Has anyone been having this problem? As I stated, I do know how to get home on my own but I am not sure why the navigation doesn't direct me straight there instead of providing a circuitous route.
