i have messed up i think. i want to put a comand unit in my 2001 clk coupe but i dont have a clue. i have a a163 unit and think i need a a208 unit. can i use the a163? can someone tell me all the parts i need and where to source them? and can i use the multi function on the steering wheel and keep the cruise control. to be honest all i want is to put a decent stereo in with cd and keep all the multi function stuff and cruise control working.....one option i found was alpine do a fix for the clk multifunction so a compatible alpine stereo will use the functions on the steering wheel but the cruise control is disabled.....anyway the part is kce-868b. i have rang around and people have said there is moore stuff coming out in the new year but please please please can somebody help me please. i have read the threads about fitting comands but there does not seem to be a parts list.........
