[mkgmap-dev] Routing

I can build routable maps for my Garmin. However, I can search for any street names. ie: I can navigate to an intersection and say "go-to" no problem. But clicking on the find -> address. Nothing comes up. I'm trying to determine if this is a problem with mkgmap or the source OSM data. Can mkgmap handle the searching of names? and if so what data is required on the OSM side to make it work? Mikey
