@smallcircles Huh. Perhaps it just doesn't like my phone? Might also need some kind of poking at after the download? I'll try again if I get a moment. I can't say I'm happy with Google Maps or (worse) waze. Knowing it should work just means I need to debug.
@smallcircles It turns out that street data is not present for my area in the Open Street Map data. Which makes this cool, but not really useable for me right now. I'll try again in a year or so.
