Use forscan and use as built. Find the seats and indicate that there is no seat for all seats. This disable the seat beat chime and the start up seat display on the dash. I have a 2024 lariet. No issues by doing this.
I used forscan on my 24 F-150. Use as built and remove the seats completely and you will have nothing in the dash about seat belts at all. Not even the red seat belt light
I just got my new 2024 lariat with the unleashed b&o. It make the old 21 look awful. Volume 5 is like 16 used to be, before the update. That was my fixed for this audio update. FORD Sucks.
