My MB CLK430 was pretty easy. Only trick was I had to pick up a scosche line output piece, because the bose input signal HAD to be 5v for it to properly function. My MB was as simple as any other radio minus the scosche piece, and needing to connect the factory amplifier to the remote power of the CD Player for it to turn on properly. It was a 2003, the year before fiber optic took over. Came out really nice too, with a JVC Avx800 and some jbl components running 150 rms per speaker. Not to mention a 16v system in a mercedes.. lol.
