XZBMW  G20 RAM_HIGH harman/kardon
Hello, 


I retroffiting G20 from RAM_MID SDARS US (B274 Date 8/19) to RAM_HIGH DAB ECE (B277 Date 22/20) with BOOSTER. 

After coding it has no sound from MGU, only notifications. When I try volume up, it shows (No source available). With ISTA I can start Frequency test and everything looks good.

Things who tried to do:
Delete 676, add 688 and code MGU,RAM,BDC,KOMBI,ATM2
Change Zeitkriterium, Typschlussel
Coding with US FA
Coding with ECE FA

But always No source available
When I plug RAM_MID, sound come back.
