Osmand's default map is drawn by the offline ondemand renderer, and that requires a download (there's the full blown map data and a road only version with ⅓ the size) There's also the option to enable tile based online maps from a number of predefined providers, if you know the url scheme you can also define a new satellite or traffic tile source from certain known providers (and set opacity) to show those tiles on top of another base map
