Purchased a 2012 C-250 today. I have problems
 

Everything was good on test drive. After going through purchase I noticed a warning that lane warning was not working. On further examination I noted that all buttons on steering wheel did not work. They did work on test drive. No voice command, no phone, no volume control, no menu.

Kind of depressing. I called the dealer and they said to bring back car tomorrow. Any idea?

Cheers
