Look at the ways around the POI. Could the nearest routeable way be a 
routing island (not connected to the rest of the road network, for 
example because of a missing junction node)?

I experienced this some years ago in the center of Helsinki. One POI was 
reachable, because there was a highway=residential near it. Another POI 
next door (some 20 meters away) was not reachable, because it was in a 
highway=pedestrian area, which at that time was not translated as a 
routeable line. The nearest routeable way was some corridor in a 
shopping mall, which ended at the boundary of the highway=pedestrian 
area. My Garmin Edge 705 would choose the basemap for routing to the 
'unreachable' POI, unless I renamed the gmapbmap.img to hide it.
