I own a 2012 X3 2.5i which I purchased just over a year ago. I use the navigation system occasionally and while it sometimes has lead me astray for the most part it's ok. The Points of Interest, however, is totally useless, often finding nothing nearby or listing locations 100's of miles away. Has anyone purchased the 2013 Map update? Besides the fact that BMW is again screwing its customers by charging almost as much as Tom Tom charges for a complete system including free updates, I'd hate to purchase the update a find it still has the same problems.
