C63 Steering wheel swap?
As far as the buttons maybe you might be have to program them, or they could work out of the box.
Now as far as the airbag system goes, some cars (not sure if it applies to mercedes) use different volts to power it, so I would be EXTREMELY CAREFUL as it could blow up in your face if powered on. Talk to a some shop that does aftermarket stuff for mercedes just to make sure.
I have also thought about doing a steering wheel swap from a maybach but the airbag issue is what worries me, if it was one of my other cars i could careless about a air bag lol.
again the only way you will find out is thru trial and error, uninstall your old one and put the new one on if the spline size is the same bamm you got a new steering wheel, turn on the car (with out hooking up the air bag) and see if the buttons work if they do bamm you got buttons that work. As far as the air bag umm..... i would consult with someone that is good in that area lol
