Another neat 480 feature is that it will sequence you around to the
missed approach point again without any manual twisting or SUSP button

the 430.

I have noticed that. I was wondering what would happen if you were
flying an approach that callled for an immediate climbing turn on the
missed. If the pilot didn't disengage the autopilot and was getting the
plane configured for short final and all of the sudden the plane
started turning. It would be especially odd for me since my plane was
certified with a full time autopilot. As a result, when I press the red
button on the yoke the autopilot disconnects, but when I release it,
the autopilot comes back on. I did get a POH update though that allows
me to pull the breaker out (which is actually how I fly most of the
time local) but that means I'm flying around with a big red warning
light on that I have to explain to passengers "This big red, annoying
light just means teh autopilot is off".
