Hi, I've discovered some routing hickups I don't quite understand. Here is a link to the motorway ramp/exit in question: http://www.openstreetmap.org/?lat=50.90594&lon=11.0078&zoom=15&layers=B000FT... Trying to route from the 'B4' (coming from north) onto the 'A4' going west fails. It looks as if the ramp going onto the autobahn is not connected. I've observed this behavior on my etrex legend (compiled with data some weeks old and mkgmap r925), but also today with recent data and mkgmap r975 routing with mapsource. I've looked through the osm data (in JOSM) but found no irregularities. All nodes are connected, there's no oneway in the wrong direction or anything. The ramps are tagged with ref=A4;B4 which seems odd, but I don't know the proper handling of ramps regarding ref numbers. To go east onto the A4 seems to be no problem. (To turn around on the next exit is the proposal mapsource gives to me to reach my goal). the only difference I can see between the western and eastern ramp is the node with the traffic lights. Could someone investigate any further? Thanks Stefan
