I just took delivery of my new 2006 LT. I was told by the sales rep that my helmet headsets from my 2003 comm system would work with the new bike. Apparantly they don't. The pinouts seem to be the same - the plug fits, if that means anything. But, alas, no sound through my helmet headsets; not from the radio, intercom or cell phone. Does anyone know if the connecting cords are compatible, or is there something else I might be missing? Thanks.
