Just dropped my truck off at dealer. The only steering wheel controls that work are the cruise control buttons. Problem started at odd intervals, one day it would be fine and for no apparent reason would not work the next. Finally, all but cruise control stopped a couple days ago and hasn't come back: Volume, track skip, driver info center etc. They tried disconnecting the battery for 30 minutes to reset the communications and that didn't work. We'll see what happens and I'll post up when I get truck back.
