I did a Harman Retrofit on my BMW 3GT. Which modules do I need to recode?

Is there any need for ISTA+? I have only E-sys.

I have VO-coded my car with 688 and recoded NBT_HU, but still no sound. I can't see any AMPT ecu?

Appreciate if anyone can share some experience and information.

Thanks.

Sorry to dig this up, but did you succeed? Doing this now as well but can't get amp to turn on. Did your amp have ASD?
