Please confirm that you want to retrofit the widescreen COMAND2.0 system (i.e MY2003) and not the earlier Comand2.5 system

If you are doing that, I suggest you use this adapter loom: -

Comand Online Ltd :: Mercedes SatNav/COMAND :: COMAND Retrofit parts :: W203 last C Class & CLC, W209 CLK, W463 G :: Comand wiring loom adapter for W208 CLK, W210 E, W203 C, W209 CLK, W463 G Class
