At this time Address lookup works with Tiger maps only. Rewriting for OSM is going to be interesting. Tiger maps are by county and zip code. When you search an address, it knows which maps are in the state your address is in and thus knows which group of maps to search. If you specify zip code, it pretty much knows which exact map to look in. OSM maps are by coordinate/maptile. So there's no way right now for the App to know which map database to look in for the address. (for OSM online address search via google maps may be the easiest option...)

This is one of the reasons that RoadMap is marked Beta/Stable at the garage. The program is Stable and the features work well with Tiger maps, but OSM support, (having just been added) is in Beta.

As I get reports of what works and what doesn't, I'm going through the code...
