For rider to rider coms, you do not need the CB. That feature is built into the radio.

I'll have to check to see what purpose they want the CB for. If its just for coms, what would they need to get that to work? I would assume there would be plugs for the helmet dongle wiring?
Right...they would need headsets. The plug for the driver is usually attached to the fairing. The passenger plug comes from until the seat...but I am not sure if it is a standard thing. (I think it is...but not sure.)
They would hit the V-Mode button on the radio once...and then increase the volume until they hear each other. Remind them that the intercom is live all the time...those innocent comments made in one's own helmet would be heard by the other.
