2001 Acura MDX - Steering Wheel Controls Not Working

I have a 2001 acura mdx 83K miles and the "srs" light came on and gradually all of the controls on my steering wheel stopped working. First the cruise control, then the radio controls and now the horn? Any suggestions as to what might be the problem??

Thanks

Sounds like the "clockspring" has gone bad. that is the contact plate between the steering wheel and the column .

Is that a diy job or dealership??
