2009 MBZ E350 W211. I have been trying to get my car stereo installed but was hesitant due to the Fiber Optic connection in my car. I found Enfig by accident though Google on "how to install..." and they popped up in a YouTube channel. Watched the vid in it's entirety...Ordered my hardware, and Christian is awesome answering the questions I had when I installed my Kenwood DMX1037S using their harnesses and reverse camera. Everything is working the way it supposed to be and the rest is history. Their parts are truly plug and play. I still have my Steering Wheel Control, and my dash clock still syncs with my radio. My local Car Stereo store would have charged me $1450 to get everything installed with parts. Thank you Enfig! Your store and product is highly recommended. I may have to order the Dash Mounting Kit since the one I got from Crutchfield has little play even after tightening the bottom screws that holds the radio from sliding out.
