OK, I uninstalled it and then installed it again and now it seems right. I downloaded the US west map and it works.

Why do you say this is "worthless" iball? It seems pretty handy to me. I have an N800 with no GPS. This map doesn't cost me anything and the places I know seem pretty accurate. I can search for streets in places I don't know, and it even finds hotspots at Starbucks. Seems like a good thing to keep around.
