Hi Matt, thanks for your question! I am not seeing that the Scosche LPMZ25 Wiring Interface is a fit for your Mercedes. Based on the info I have pulled up on your year make and model, I am seeing other options available. Please chat with an Advisor online, or by phone at 1-800-324-9695. They will be happy to be sure you're getting the correct gear for your stereo upgrade!
