Keep CD Changer AND add RaspControl?

[Baddabing]

step by step
do you have selected audio mode aux in addon settings?

Hi Harry - no I have not.

In fact, I have not built my system yet.  Does this setting enable iBus communication?

As I said before I would like to keep Intravee and try another approach - but perhaps the approach below is (also!) impossible/too difficult.

So - if right-hand control on Bordmonitor in Aux mode would work then I can use RPi3B+ on HDMI into new screen AT065TN14 or is there 'no signal' or 'no traffic'f for iBus?

Thank you for your patience.
