Hi Thomas, there is not much that you can do besides coding a better solution. We need code to - process the administrative boundaries which dvide drive-on-right (dor) and drive-on-left (dol) areas so that roads are cut there - so-called external nodes are written to make routing across tile boundaries work My understanding is also that mkgmap might have to process tiles twice when they contain both dol and dor areas. This is not a simple change, therefore nobody tried to code it until now. Reg. routing: The problems are rather small. You can expect wrong routing on roundabouts (wrong direction) and probably wrong penalties for sharp turns at road junctions, as a left turn in a dor area is more time consuming and wrong setting of dor/dol will produce false preditions of travel time.

The img-file is successfull created and routing works in Mapsource. But is the routing correct ? Tiles contains many different countries. What con i do to prevent the warning ?
