I was going to comment that CB band is not UHF but in Australia apparently it IS.
I think you need to contact the maker of the radio or the headset for help with this.
My guess is that you will NOT be able to transmit from your stock common headset but will need to be connected directly to the UHF radio for that.

I didn't have good success with my motorola XPR 7550 bluetooth to the Sena 20s. It worked only part of the time.
I'm on Ham band btw.
