So I finally got my 187B Factory Carplay unit installed and had to do some VCDS coding after (using the latest version of VCDS). Here are the possible tweaks to the unit:
Yep, just noticed in the VCDS 17.8 release that the long coding for the RCD330 now has labels. I have the Dynaudio system so I tried changing my coding to the following:
Byte 1: 05 Dynaudio Sound System
Byte 2: 00 Sound System (active Speakers)
Byte 4: 01 Treble Speaker Monitoring deactivated (Sound System)
However, when I click "Do it" it throws an "Error 31: Request out of range" message. Also tried Byte 1 with 01 "Volkswagen Sound System OR Dynaudio System", but that gave the same error.
Sound is working, but figured I'd try to code it to what seemed to be correct for my setup and see if I could hear an improvement. But no luck...
