Ron,

This is very disconcerting to the passengers, and
if I was really flying the approach in IMC, you can be assured that this
would be extremely disconcerting to me!


I wish you the best for resolving the problem, but as an aside, you're
putting way more trust in a non-certified handheld device than I ever
would. What you pay for is what you get. The ILS you're following down
there IS certified, as is your receiver. I don't think the 496 nor its
terrain database were ever designed to do close range avoidance. Trust it
when avoind terrain by miles, not tens of feet.
