2009 clk 350
I can confirm that using the part numbers in this thread, it's a plug n play upgrade. No splicing, no cutting, all surprisingly easy. In mine, I only needed the voice input handle and not the entire switch. So no dis-assembly of the steering column other than to pull out the plastic plug where the voice input handle goes.
All necessary wiring is indeed already in the car, including the most fiber. Note that the mic input that has to be switched over to the voice input is located in the trunk, in the same wiring bundle as the rest. It's located underneath the carpeting and under the plastic panel that the cargo D-rings bolt through. Remove the 2 D-rings, and then that plastic cover panel and you have access to everything you need. All of it is clearly labeled.
Super stoked about this upgrade! Now I just need to figure out how to use it correctly.
Thanks xriston for doing all the research!
