Are there any motorcycle riders out there that use the 650 with a Chatterbox on their motorcycle? I have been putting my helmet on over the Treo Stereo Headset so I can listen to music and answer the phone while on the bike. It takes several attempts to get the helmet on without the ear pieces being displaced. The built in speakers and mike from the Chatterbox would be ideal but I don't know what cord I would use to connect the phone and the box. It would have to be a compatible male plug in on both sides of the cord. Has anyone linked these two yet?
