Without a basemap, the 705 says 'error in route calculation' straight 
away. If I click on the Aussie bar next door (some 10 or 20 m away), it 
will calculate a route. Could the error be that an access=private 
highway=service on layer=-1 is closest to the point, and Garmin fails to 
choose another road? (Usually, the routing algorithm seems to want to go 
to the nearest road, and then the shortest distance from the road to the 
point.)

I guess that the fix is to draw a cycleway across the highway=pedestrian 
area, in front of the shop. That should take care of this, and also 
allow better routing in the area.

BTW, is there an easy way to remove the highways from the basemap? The 
coastline is somewhat useful. Without a basemap, one cannot see the tile 
borders when zooming out.
