trouble with steering wheel radio volume after removal.
I have a 2006 C230 with factory radio. Last weekend I removed the stock radio to do a little work behind the dash. Upon completion of work I reattached the stereo connections and reinstalled the factory system.
However, once I finished and went driving I noticed the steering wheel volume buttons no longer work. They worked fine before. All of the other steering wheel buttons work. Is there a connection or something I missed when reinstalling the stereo?
Any help, please.
Thanks
Can't think of what I did wrong? I put everything back in place.




you need to pull it apart and see where you messed up.
Reseat all your connections.
Test it BEFORE you put the dash back together.
I just can't figure it out. I took pics for reference so I knew where everything went back to and I "thought" I attached everything same as before. I guess the wire or wires that control the steering wheel volume buttons must have become disconnected somehow when I put the unit back together.
