I was thinking about changing the stereo in my car however i have a small remote mounted to the side of my steering column which allows me to skip track, change volume etc. Does anyone know if in general these have a standard control signal such as RS232 or RS422 which would work with aftermarket radios or would i be doomed to have a useless lump of plastic sticking out forever?
My car is a 2004 Ford Fiesta 1.6 Ghia
