I think it would absolutely awesome if one could combine the FM receiver with Ovi Maps, so the navigation app could use the traffic information available on FM frequencies when planning routes. As the N900 has both an FM receiver and a GPS, i think this could improve the navigation experience quite much. More info on TMC here: http://en.wikipedia.org/wiki/Traffic_Message_Channel
