If your Mercedes doesn't have a factory CD changer, here's your chance to purchase a genuine O.E. CD changer at a great savings. We got a terrific deal on these CD changers from Germany and are passing on the savings to you. Nearly all late model Mercedes are prewired for CD changers, so it's just a matter of drilling for a couple of mounting screws, then simply plug and play. (Initialization of anti-theft circuitry by an authorized Mercedes-Benz dealer may be required for some models.) CD changers come with a 6 CD magazine.
