Project is on hold due to lack of funds and spontaneouse purchases of a new PC and cell phone (G1 ;-).
Next step is new audio.
I also decided that a commercial release of the nav/frontend was useless because I cannot keep up with the major players' features, such as google streetview. I mean, seriously, how can any nav system compare with streetview??
But I will probably release an integrated frontend/nav eventually for cheaper than the competition. If I do, the UI will be open source and driven by a closed source .NET assembly.
