Hi all, as this is my first post please forgive me if I am covering old topics. It's just that I am struggling to find an alternative aftermarket stereo for my 05 CLK convertible. It is the trapezoidal stereo that is 254mm across the top and not the slightly later 260mm of which there are many aftermarket stereos. If anyone has had the same problem and overcome it could you please tell me how you did. Thanks, Richard.
