I would like to know if there is anything available yet that enables LBS apps to integration route finding and navigation capabilities. I do not want pure landmarks or POIs. I want to show on map the directions in real time from point A to point B (normal navigation stuff). Is there any API open for developers to achieve this?

I read about Maps and Navigation API in the forum but could not find it anywhere! Not sure if i missed something. Also i read about the Ovi Maps API which is not released yet. Any one has idea of the open possibilities?
