[mkgmap-dev] Gap in the street and unusual routing

Hi! One street shoes a gap that does not seem to be in the osm data: http://www.deltadelta.de/nmz/sc21.png vs. http://www.openstreetmap.org/?lat=48.08617&lon=11.50167&zoom=17&layers=B000F... I tried to navigate to the "Bad Forstenrieder Park". Since one can not pass this gap, the route went to Drygalski Allee, Herterichstr, then right and then to the grade3 path through the farmland. But I used car/motorcycle. What have I to put i which file so that routing goes not across unpaved tracks? TIA, Dani P.S: mkgmap 1597
