I have with very limited success been able to use my CB with the Freewire and 20S. I can almost always hear the CB if the BOOM system is set for audio from the speakers, but cannot broadcast on the CB in this configuration. If I switch the audio to the headset, I don't have much success hearing the CB and sporadic success broadcasting.
Where do my settings need to be in order for this thing to work properly? There has to be a trick that I am missing. I have even tried unpairing from the passenger when I try to talk thinking the 2nd headset may be taking preference over the mic to the CB, but it didn't seem to make a difference.
I also know that these features don't seem to work if you have the BOOM intercom turned on.
