I don't think he ever said that he wanted to disable the chime for when he was driving down the highway, maybe he does, but I will be doing the same thing to mine and not for highway use, I always wear my seatbelt when driving on the highway. Its when I'm down on the hunting club or on the farm checking fences that the chime really gets annoying, at least my 03 does not do it, soon my 08 won't either.
