Sync 3 upgrade from sync 1 reverse camera not working also with equalizer

i upgraded from sync 1 to sync 3 using and doing so i lost the funtionallity of my revers camera and the equalizer and also the steering wheel controls. I have tried to do different forscan numbers for the reverse camera and nothing works my screen just stays on either applecarplay or normal sync screen. ( the sync 3 screen and apim came out of a 2019 f150). If anyone can help me that would be greatly appreciated.


SYNC Region: NA

Navigation Variant: Nav

Manufacturer Year: Pre MY20

Install Type: OEM

Old SYNC Version: 4.6

New SYNC Version: 3.4

Do you have a error message, if so what is it?
none

Update Method: Official Ford

This would mean you’ve got a problem in the APIM config.

You can’t use the factory AsBuilt for your vehicle, the easiest would be one from a 2016 F150 with similar options since that is the first year the F150 had Sync3.

First thing you need to realize is that a 2014 F-150 is CGEA 1.2 electrical architecture and a 2015+ is CGEA 1.3. The two are different, but this swap can work but you will need to customize the asbuilt for CGEA 1.2. Your current Sync 1 asbuilt is mostly useless. You will not be able to have some systems work from the Sync 3 screen, such as HVAC. These are different formats and are not compatible between the CGEA versions. Another obstacle is the Sync 1 to 3 conversion. Many of the wiring kits are not 100% correct, so issues there might surface, especially with cameras.
