It's time to eat humble pie. I managed to create a single tile with all the places and roads on that I've been testing and this chooses exactly the same route as the inter-tile file. It seems it was just a coincidence that the routes hit the motorway around the tile boundary.
Sorry, my testing gaves other results. If I create a map with two tiles, then border crossing takes place at a secondary street with a rather inoptimal route. If I compile the same map into on single tile, then routing works as expected.
So you have a residential crossing a boundary that's not routed through, right? If you try to route just from one end of that street to the other, the route also takes a detour? If that's the case, things I'd try to check next were: * running both tiles through test.display.NodDisplay, does the point where the road crosses the boundary occur in NOD3? * do things improve if you thin out the residential (in the .osm, before passing to mkgmap) so nodes aren't too close, and there's no nodes close to the boundary Cheers Robert
