The APIM (Accessory Protocol Interface Module) is the control unit in Ford vehicles that manages the infotainment system and the touchscreen (Ford SYNC 3 or SYNC 4).

You missed the sarcasm.

What model is the APIM? They range from G part numbers all the way to N.

Did you run the interrogator before performing the reformat?

The symptom you describe would be the common result of doing a reformat of am APIM which has the newer IC in it that some refer to as MY2020 hardware (and yes it can show up in cars made before 2020).
