Snowy, you don't have to get a specific model for your car. Any Mercedes MC3xxx series fiber-optic changer made from 98-2004 will work (ex: MC3010, MC3198). It doesn't matter what car model it came from, it will work. Just don't get a changer made after 2005 such as the MC3330 or MC3520 because it definitely won't work in your car.
