Learn something new everyday! :D Actually, it COULD be done. I don't think it would be THAT big of an increase to the map size. It all should The Netropa software just isn't my cup of tea. I MUCH prefer Garmin and the Dash maps. Plus, at this price point, there are much better Sat Nav's out there. Interesting. Learn something new everyday! :D

I've never been a big fan of the Intellinav software either. What's interesting is the map innacuracies you mention. Intellinav generally uses Navteq maps which, in the U.S. are generally considered to be more accurate than TeleAtlas maps (which are generally considered more accurate in Europe). I've just started working with OCN8 which uses TeleAtlas maps and some of the old innacuracies are still there. Address innacuracies happen because roads and address blocks are stored by road segment. Most software divides the addresses (in most cases) evenly across the road segment. That way the sotrage of address dara takes up less space. You're right, though - even the online maps line up things incorrectly. I don't think this will get resolved anytime soon since it would mean storing exact locations for millions of addresses. Can you imagine what that would do to map size? i gue4ss they figure if they can get you on the right block you should be good to go.
