EDIT: This post is no longer necessary - the full map has been released and is available HERE.
Here is the poi.dat from the NA 860.3101 full map.
The full version of the NA map was not released in the 855 series and so far, not in the 860 series. This file seems to be the main difference between the two maps. I compared the 850 full and 2 GB versions and they were almost exactly the same size except for poi.dat.
