I am currently in the process of installing a double din headunit in my w204, just waiting for my dash/face kit to arrive for me to install it. Would anyone have an easy to read wire diagram? I found a few wire diagrams already but its a bit confusing. I have the rear and front speakers figured out. I tried messaging two people that have installed aftermarket headunits on this forum but have not responded back to me. Any help would be great

Thanks in advance!
