Nice! I was just looking at this last night while searching fruitlessly for an image of any updated NavTeq CD or DVD. It may be possible that the DVD data can be segmented and used to update the CD data as well. All that would likely need to be updated is the Main Db and POI files.

I'm going to attempt to decompile the actualy map data this weekend to see what's in there. I'm hoping they didn't use anything proprietary when putting these together.
