I've seen that as well with a 430. More than once. And I think I've
even seen it in the PC simulator from Garmin's web site. But I
couldn't reproduce it. I think if you get well off course as the
needle sensitivity increases (just outside the FAF), it may bump you
off like that. But I never found an explanation for all of the cases
in which it happens.

I confirmed it wasn't a RAIM issue and I was dead on the approach course. I
even pressed the arm/actvate button but that didn't help.

Garmin says it might have to do with the setup of the unit not interfacing
with the annunciator panel. However, I'm getting the MSG light on the
annunciator panel so I don't think that is it. They are checking on that
and said they will get back to me.
