Retrofitted sync2 but no sound when the car started

Ford Non SYNC 3 Support

I have retrofitted Ford Sync2 to my focus. The Sync itself was from US spec car with 10 Sony speakers with DSP I believe but my car have only 9 speakers without DSP.
I look at the asbuilt file and I see the DSP line but my car doesn’t have DSP
After installed the car have so sound but when I turned off the car the sound was coming out but cannot adjust the volume. I tried swap the old ACM from Sync1 and it is working the sound is coming out but I cannot enter the entertainment page. Voice activation, Bluetooth, USB iPhone is working can skip song and everything

so I was wondering what I have to do to make its working properly
thank you in advance I really appreciated your help.

You will need to adjust the APIM asbuilt with FORScan and an OBD adapter. You will need to disable the DSP.
This will be the first line of the asbuilt. At the position noted, you will change the value to 0.

I have tried but still not working maybe I have to try every combination tjat start with DSP Disable?
Does it have something to do with ACM? In forscan it shows DTC that ACM lost communication with digital audio processor D

Probably. Can you post your ACM and APIM asbuilts…
