AUX lead to control Galaxy s2 through stock stereo Audi A3???

[Simon170TDI]

Is there such a lead that will allow me to control my Galaxy S2 through my stereo.. I know aux leads don't do this but wanted to know if you guys know of anyone that's brought out such a lead. I've searched tonight but can't find any :/

Your help would be awesome
