AC control issues after upgrading from 5 inch to 8.4 radio

[Apny2nv]

I just upgraded my 21 1500 DT from 5 inch to the 8.4 screen. I purchased a used 8.4 full stack, but the unit came out of a 21 Laramie with the Auto temp AC controls and heated seats and steering wheel. My 21 1500 had the 5 inch with single zone system. I installed the unit and it was pretty much plug n play. Radio and uconnect works great, I did have to put in the radio security code. My only issue now is I cannot control the AC system. Is this something that can be corrected with Alfaobd , or will I need to change the bezel to the signal standard AC controls and no heated wheel or seats?

What would that setting be in Alfaobd? The strange thing is that I put the original unit back in and now I'm still having the same issue with the AC system. So the radio has to match the HVAC system the vehicle had?

Changing the bezel to the standard AC controls might be a simpler solution. Consult with a knowledgeable installer or a dealership for guidance.

I have a new bezel with the correct controls coming so I'm going to try that first. But now my concern is that there is still an issue with the controls even after I put in the OG radio and controls. I'm wondering if Alfaobd can fix that... I just Don't know what command that would be.
