Double clicking is _not_ a good idea. I'm lucky if I can get my
normal radio to turn on one time out of two. It's one push for on,
one push for off, and it's just blind luck whether I hit the button
an odd or even number of times. Doing this on 4 buttons is going to
be a nightmare.
(The wired remote for the steering wheel looks ever more tempting...)
