I have a 2018 F150 Lariat with the 8" screen and B&O sound system. I have updated my system to V3.4 using the CyanLabs tool. Recently I retrofitted a 2018 Expedition FCIM into my truck. It provided additional controls not available in the F150. Namely a physical heated steering wheel button.
Anyways, I have installed it and it is mostly working. The only issue I am still battling with is that when I enter the vehicle or unlock it, before I start it there is no illumination for the HVAC controls until I actually start the truck. For example, when I remote start and I open the door, all of the controls in the truck will illuminate, except for the HVAC controls.
I suspect I need to change a bit somewhere in the as-builts for the APIM, ACM, or FCIM but can’t find the correct one. Can anyone provide me any assistance as to where I should be looking. Thanks in advance for any help.
