2011 Mercedes Benz c300 (w204) head unit install /w retaining factory features.

[Jones20992]

So I have a 2011 c300 with the audio 20 head unit and I would like to install an aftermarket head unit but would also like to retain the ability to use the steering wheel controls as well as the rotary dial in the console and the display in the center gauge. Is there any way possible to accomplish this?

I have seen 2 install kits

#1 Axxess XSVI-9005-NAV Wiring Interface

#2 Spiral Audio BV-MB009

But I am unable to find any specifics as to what features are still available and which ones are lost with either these kits

I doubt it, Mercedes cars have very complex wiring, you can run into major problems if you don't know what you are doing.

Try one of the Mercedes forums, maybe someone has done the hard work for you
