I have seen it when the way closest to the destination point in the 
mkgmap-generated map is part of a "routing island". I guess that we 
should consider translating highway=pedestrian as ways (not areas) in 
the default style, to fix this problem. I fixed it by adding a way 
through the pedestrian area, but it is only a matter of time before 
someone "rights this wrong" by deleting the routing way again.

In "demo mode", my Garmin Edge 705 even jumped my current location 1 or 
2 km to south so that the route would start closer to a way on the 
basemap.

There is http://wiki.openstreetmap.org/wiki/Mkgmap/known_issues. This 
problem does not seem to be mentioned there.

Are there "routing islands" on commercial maps? Are there tools for 
checking that in Garmin maps?
