Hi Daniel, there should be no problems with routing, because a route should switch maps at the country border. See mkgmap option --add-boundary-nodes-at-admin-boundaries. If you don't like tiles without full content, then use bigger extract and smaller poly file as an option for splitter. See splitter option --polygon-file. Other possibility is to split bigger extract (for example Europe), convert all tiles to img and then create lists of tiles for each country you need (for example Germany and France). Then you can run again mkgmap with list of img as an input, to create separate maps. Unfortunately rectangle tiles causes a problem for address search. If you are near the border on a tile shared by 2 maps, then GPS could use wrong map for a search. Proper solution would be to have irregular tiles cut at an administrative border. This is how original Garmin maps are split into countries. -- Best regards, Andrzej
