Had a look at the Demo, every window is taken 1:1 from the ‘Tourenplaner’ (but translated, as the Tourenplaner is only available in German as far as I know). Tourenplaner map data is from Navtec, Spain, Great Britain, Irland, Portugal, Sweden and Norway are not included (and available for the Tourenplaner), on the other hand the whole of Poland, Slovenia and Czech Republic are mapped in detail.
If the huge difference in price comes from including the missing countries it would be great news as I prefer the Tourenplaner to MapSource and it probably would be available there then soon as well, if it is for the translation only, even if it would be Dutch and English…….
I like the height profile you get with your routes and the possibility to route along scenic roads (the ones with the green stripe running along on paper maps) and the ‘Round Trip Feature’.
Transferring routes to MapSource (where one has to recalculate) is straight forward (the Tourenplaner opens Mapsource with the route for you) and so far I have seen no real differences in routing after recalculating.
For your routes you get online access to the ADAC travel information for the day (roadworks, traffic jams, etc) and to weather information, all of that can be integrated into the road book.
There are also lots of routes (around 900) already in the Tourenplaner.
If only Mapsource could have some of those features as well.
