Thanks! I just recompiled a map of Germany with r911: I am very happy
to report that inter-tile routing does work for my initial, simple
test cases in Mapsource.

I can also confirm this behaviour: in a test crossing multiple tiles
over a long distance (from Heilbronn to Cologne), Mapsource attempted
several recalculations and then drew a straight line from start to
destination. When I added an additional point to the route, Mapsource
immediately recalculated the route correctly.

Later on, I'll try some further tests on my GPS unit.

It's great to finally have this feature -- even with small inconveniences.

Cheers.
