I am always flicking between different stations in my car trying to find a station actually playing music rather than a constant stream of adverts or talking. On my presets are Radio 1, Radio X, Capital, KISS, Absolute and Heart.
To fix the error D3DX9_43.DLL you have to download just one file from a trusted source. Last time I used fix4dll.com/d3dx9_43_dll . So now everything is functioning effectively.
