Radio upgrade

[Clint]

Hi
I want to fit a pioneer fhs820 dab stereo in my 2009 clk220cdi sport but I'm not sure what fitting kit to use, does my car have a factory fitted amplifier?

First port of call is comand.co.uk with your VIN so they can look up the build sheet and see what your car left the factory with, they can then tell you what you need to achieve what you want to achieve. If you're close to J3 M3 (no approx location in your profile, suggest you fix that!!) and could no doubt supply and even fit!
