Been riding Harleys for a long time but have never used the Premium Headset that came with my last two bikes and now the one that came with my 2020 Tri Glide. Trying to figure out how to use it with the Boom Box GTS. Plugged it in and it doesn't work. I'm sure I am missing something. Is a Boom Box GTS flash required? Instructions reference a software update for older HD radios but nothing on the Boom Box. Other setting/config? Thanks for any help!
