After joining a few months ago I posted a message about a problem with my 2008 RS CB unit. The problem is when keying the CB unit to talk, in the controller window , it would say CB Error, and the CB unit would not work. The dealer has replaced the CB unit and all related hard parts but the problem still persists. After much discussion with Yamaha Tech they feel the problem is within the main wiring harness that runs from headlight to tail light. Yamaha has auth the replacement of the harness and it has been ordered, but has to come from Japan. Just in case anyone is interested I will post a message after the harness is installed to let everyone know if it fixed the problem.
