I want to use riderunner and ibuscomm to connect my carpc to the HU (Headunit). I have my ibus adapter connected to the ibus and turned cdemulation on
Attachment 63823

Now when i select the CD mode on the HU i see "CD 1 -" And then nothing happens on the HU. How can i make this go away? The steering wheel buttons work.
And how can i connect the carpc audio to the HU. Can i directly connect the left and right audio to the cd trunck cable?
