In their recently revised Body Building manual, all the information is located on page 114-116:
‘Reprogramming of the APIM and the IPMA using the FDRS will be required to allow the IPMA to display the auxiliary rear view camera whilst the vehicle is moving. See your local Ford Dealer or National Sales agent for further information on the APIM reprogramming’
‘Only vehicles with Digital Rear Vision and/or 360 deg Cameras (J3KAH or J3KAR) have the IPMA capability to support aftermarket fitment of an Auxiliary camera (NTSC format)’
