[Enable the headset plug on 2018 Star Venture TC]

I have a month old 2018 Star Venture TC with a J&M ELITE 801 SERIES HELMET HEADSET. I cannot get anything out of the audio plug let alone use voice. There must be some setting I haven't made correctly. Does anyone know this system well enough to help me through this. Since I'm 76, and so far I've written this off to motorcycle dementia. I can take instructions though. My old V-Star 1100 was nothing like this Venture.

I had the same problem and process in this thread worked for me too.
