Also, the 2019 HK unit features a CAN controller for the volume going to the factory HK amp by sending a fixed signal to the inputs then using a separate mechanism to control the volume.

I guess I get what I deserve for thinking that it would be easy to just replace the HK system in the 2019 if I didn't like it.
