I bought NEW dsp module Bang & Olufsen ,SYNC3 MONDEO MK5 ECOBLUE 2020 how do I get this menu?

On my Focus mk4, I replaced DSP with newer model. I also replaced APIM with newer. It still did not work.
Then I found I had to change APIM line 7D0-08-02 XXXX- XX1X- XXXX. Try changing 3rd digit in 2nd block to 1. Mine was 4, changing to 1 gave me that Beosonic menu. Maybe I didn't need to replace APIM. Who knows

I have already found out that the ACM unit must be directly connected to the DSP module via USB, otherwise the screen is gone, which after replacing the BO DSP will not display, but the sound will still be great.

FW of DSP maybe needs to be upgraded. and try to modify:
DSP 783-01-01 xx1x xx
APIM 7D0-01-01 xxx8 xxxx xx
APIM DE07/7D0-08-02: xxxx-xx*x-xxxx ( modify this to 1,3,5,7,9,B,D,F ) to enable BO Tone Touch.

This is great, but how can I download the new software for DSP? I hope you can help me.

Sorry I am not sure the DSP firmware version. there is a specific firmware number for different ford vehicle, and you need to get the latest beta version Forscan to update the available firmware. it's complicated and have risk making the DSP is blocked.

anyway I tried to find the As built data from this link:

and see the #79.

good lock
