Ah, well. Maps aren't enough. It's tougher to write good navigation software than many people think. Sounds to me like TomTom solved the problems reported in Navicore years ago. For example, my 2004 version of TT comes not only with regional maps, but also with a special map called 'major roads of Europe', and to navigate from Paris to Wien (Vienna) you just load mjoe and off you go. Then, if you need to go to some minor road not covered in mjoe when you're near your target you just switch to the local region. I believe it's an even smoother operation in newer versions of TT (I bought TT5 too but as I'm happy enough with the older version I've yet to install it).
