USA maps are blank in gmapsupp format?

I’ve been trying out these maps, using the auto compiled gmapsupp.img format that I can download straight to my Gamin 60CSX
The European maps work fine, but the US maps seem to be blank - no roads or anything. I selected a bunch of northeastern states, from Washington DC to Portland maine, and the file size seemed rather small.

any suggestions? do I have to use Mapsource for USA maps but not Europe? the added step is a pain…


No, the tile splitting process is apparently broken for parts of North America. The resulting tiles contain only POI’s for some reason.

I’m in the process of moving to my new house, so I don’t have much time to work on this project for the next two months.

Any updates on the US maps working?

Nope, still busy renovating my new house.
