Using the reformat tool would have disabled a MY20 screen, since the drivers are not correct. All you need is an older model screen to get the unit working. However, the screen you show, KS7T-18B955-SA, is not a MY20+ screen, and should work fine. This is the same as a KL3T-18B955-SA (2019 F-150 screen.) with different brackets for the vehicle model.

Additionally, the APIM you bought is an actual replacement APIM from Ford. This unit is straight from the factory, has never been programmed to a vehicle. The asbuilt is factory. You will need to copy your asbuilt from the old unit to this unit BEFORE you do anything else.
