Lots of cars sport the big red button, but on others I've owned it hasn't been as prominent (like on the steering column). Am going to try to prise it out and do something about it.
Have not found any literature to say I can't change its colour. If it is illegal to do so, shouldn't the manual state that you can't change change it? I think it dangerous as its distracting me while I drive.
Considering fitting a silver overcoat, which I can remove at service time!!
