Does anyone know why the accessories catalog shows the sirius radio and the CB radio not available for the R3-T and only through 2017?
Not sure if you mean RT or F3T, but no matter. The audio system has been completely redesigned for 2018. There was no allowance made to add the CB or satellite radio modules that I can see. I am considering getting the satellite radio next year. Head unit on the handlebars. Connected to the aux input.
