I bought the right SZL with cruise control to retrofit it. I retrofitted it and coded the new szl to my car. The buttons worked, but after i added $249 it stopped working in general. I added $540 to my vo. I am lost and i don’t know what to do. I used and autel diagnostics tool. I retrofitted sports-steering wheel $255 but the buttons will not work. When i want to press ‘retrofit multifunction buttons’ it says not available on this vehicle. I’ve wasted 14 hours on this and i’m beyond answers. Please help or i’m gonna go insane.

P.S.: the cruise control works like it should but it does not show on the cluster?
I tried adding the option $544 or which one should be the ont that show the active CC speed and +&-?
