Hi
Weird artifacts at the border I can cope with and were to be expected. The places I'm visiting are hundreds of miles apart and not near any borders so that in itself shouldn't be an issue
For routing to work across the tiles, the road end point has to be in exactly the same place (well within 3 garmin units, about 20m) on both tiles and they have to be marked as edge nodes.
mkgmap does this only if each tile has roads (etc) that extend beyond the declared bounds for the tile and that those bounds match up exactly. It cuts the roads exactly to the boundary and therefore knows that the node it inserted is an edge node.

Routing across borders isn't an issue (I'll be flying across that part) as long as I can route within each tile Cheers Paul
