I used the Chatterbox for Bike-2-Bike, Rider-2-Passenger, and iPOD for awhile but left it behind when I got the Garmin Zumo 550 and upgraded to J&M Bluetooth headset...the only input the Chatterbox allows is for external audio, so you can't get the microphone integrated for 2-way communications to a CB. I talked to the J&M folks at the Chicago Motorcycle Show this year and they said they were Bluetooth enabling their handlebar mount CB which would make their Bluetooth headset compatible with their CB. It's a totally different solution and doesn't allow bike-2-bike on FRS, but if all your crew is using CB, it may be the answer.
