I would agree. The GPS hardware is excellent, but the new TeleAtlas software and database is terrible. In the middle of nowhere in Idaho it told me to turn off of the highway onto a small dirt private farm road at least a couple of times. There have been many other similar errors, including one where it was confusing two cities in Texas that were more than 40 miles apart, e.g., it showed a Hampton Inn in city "X" in the database, and when you choose it and told the nav to go there, the city name changed to city "Y" more than 40 miles away.

Not infrequently the nav voice will tell me to turn left or right, while the route on the map sows straight ahead. If I follow the nav voice, it just takes me around a block or two to the next place to turn, and brings me back to the original route.

My Garmin software is vastly superior although, as I said, the BMW hardware is faster with a better display. So I guess the BMW Nav system can more quickly and precisely take me to the wrong place, using a bad route with inaccurate voice commands, as compared to the $150 Garmin!
