I agree. Experimenting too early = too many unknowns and risks. Navteq does the map support (says the label). I have a dvd system of theirs in another car - for that one the Navteq updates were expensive ($300 each time) and slow to happen and completely discontinued 2 years after the model went out of production. I've seen one thing on the spider system that changed in the real world here more than 5 years ago. I really don't know how they keep track of changes that are happening all the time.
