Triggering Car Kit should be easy. Just like FM Boost. Someone asked if I could integrate the functionality of FM Car Kit into FFM. I think that would be much work.

As you're a developer you could easily check if runnig Car Kit from FFM does work. If you have Nokia SDK and QtCreator installed you can add the call at line 182 of ffmwidget.cpp. There is already the call of FM Boost as an example.

I am not using Car Kit myself so it's hard to say if it is working as expected when adding this call. If you could tell me the path and filename and any needed parameters I can add the call myself and give you a snapshot package to test.
