So BCM changes definitely didn’t take, volume knobs not working

Since the 12” screen isn’t capable of single zone manual temperature control, which your BCM is programmed for, you’re gonna have to use AlfaOBD to change it to dual zone ATC and try to run the screen controls in manual mode synced up. It’ll never truly run right unless you add the in car temperature sensor and the four in-duct temperature sensors. I made a Y cable for a member on another forum so he could run the HVAC off of the old manual controls until he gets the temp sensors, I’m working on a harness to add them.What about my HVAC controls?? I have read that with the 8.4” you had to buy a separate module that goes in the panel on the passenger side ? Do I have to do the same? Wiring?

I know of a few who have. Is that where you got yours? If so, that’s why your controls don’t work at all. Their genie sets the wrong setting in the BCM, and they don’t know how to get them to work when going from a 5” to a 12”.Has anyone on this forum purchased the 12” set up from infotainment?

The genies from infotainment are VIN locked. The dealer will be a crap shoot if that sales code populates to enable for your VIN. It *might* populate if your trim level truck was offered with auto temp control as an option.I didn’t get mine from infotainment, I sourced all the pieces and purchased them all. Plugged it all in after repinning the one connector and everything worked with the exception of HVAC controls and volume/tune knobs. I was wondering if someone that did get the unit from infotainment would be willing to rent out their programmer..... if not I’ll go to the dealer and see if they can/will do it.
