Not a basemap, but a real routable tile.
    

I don't have one, but I could buy something, *if* that gives you an
unlocked, routable tile. And I'm not sure about the "unlocked" property
- if I buy, for example, a bicycle map of the Netherlands, on SDcard
(something I've been thinking about anyway, to compare the differences
with the OSM map), would that give me an unlocked map? Or a locked one?
