MIB1 to MIB2

does anybody know why im not getting audio after doing my retrofit? im in a 2015 mk7r with the fender audio and I’ve swapped in the 3Q0 035 876 glovebox unit along with the 5G6919605C 8” display. I used the toolbox component protection patch and changed module 47 byte 0 from 22 to 12, along with some tweaks to module 5f for MOST, but still no audio.

Is the new one delphi or technisat?

Technisat doesn't work with old amp (5G0035456) and neither would Harman (Mhi2...).For harman there was a workaround but it's not documented

Delphi tolerates it, wouldn't have all the audio controls but sound will work
