Bad Clock Spring?

My multi function display went out while driving randomly a few months ago and has not worked since. I thought it went bad so I took it out to begin looking for a replacement. I then recently discovered that some of the buttons do not work on the steering wheel. The horn and cruise control still work fine. Does this sound like a bad clock spring? I hate to go to all that trouble to replace but cannot think of what else it could be. All fuses are good.

 

The MFD just went out one day. I then noticed the buttons on the right side of the steering wheel (temp controls, display, and trip) were not working. I am not sure if the ones on the left (volume up/down, mode, and up/down) are working because they all control the MFD which I took out. The horn still blows. I checked all of the fuses. Replacing the MFD (this is the JBL) is very expensive so I want to make sure before I go and buy a replacement. I appreciate the responses.

 

Yes, it does have the "touch tracer" feature and was working before. I need to figure out if it's the MFD and the clock spring or if it's one thing messing up both. I looked at the post you linked and have heard that you need to be careful with aftermarket radios which is why I really don't want to go that route. I was hoping it was just the clock spring and I could reinstall the MFD and everything works.
