Steering wheel buttons not operating, my up, down, both volume buttons and DISP buttons all don’t work. Mode , voice command , and both call buttons DO work, if anybody has any idea of what the solution to this is thank you. I checked the fuses and everything is good, thanks much guys

 

I'd start by looking at fuses. Most will be system to system power grid related and nothing should be over 15Amp. Likely under the dash.
