SYNC 1 to Sync 3 retrofit

Continuing the discussion from Cannot get Reversing camera and Dynamic lines to work:

I tried your suggestion. Forscan sees the FCIM module, but has no asbuilt settings that can be changed.
I also tried to change my ACM asbuilt setting which currently states

727-01-01-0030

I tried to change it to 727-01-01-9A30 or 727-01-01-9C30 and got a message stating conflict with the ACM shows a dtc U2101

Can anyone help with these.
