I have 2002 C230 K coupe that came with the analog climate controls. I want to switch over to the digital controls but don't know for sure if it will work. I looks like it will fit..but I think there are 3 versions - 203 830 05 85, 203 830 09 85, and 209-830-02-85. Has anyone attempted this conversion and if so was there anything special you need to do?

Any advise will be much appreciated

TQ
