I would agree. I dont know why you would have to change the existing system assuming it works. The new light is not mentioned in the owners manual, so i have no idea what it means if it comes on and stays on. It doesnt mention how to set the clock either.
little button on the lower right face of the clock, use a pen or something with a fine tip to push it. The clock will advance slowly at first, but will speed up if you hold the button. The new manual covers nothing on the new style dash.
