It's my understanding that MapPoint uses several companies including NavTeq to obtain address info. We just did a big address resolution batch in the Phoenix area and found some wrongly placed addresses, a lot of missing addresses, as well as entire subdivisions that were missing. Where do I report this stuff. I went to the NavTeq site and tried submitting the errors there but I'm not sure if this is the best way since I'm not sure if they are responsible for the area of concern.
