Has anyone upgraded their GNS-430 to a GNS-430W (WAAS)?
And are there any additional hardware/software changes required?

And as a side question, if a person hasn't purchased either yet, what are
the advantages/disadvantages of a 430 WAAS vs. a GNS-480? I lean towards
the 480, but it would seem to me (I'm not that familiar with either) that
they both would do essentially the same things.

Yes, the 430 and 480 may do the same thing, but they certainly do it
differently. Based on use of both, the 430 is not in the same league as
the 480...if it is to be used for IFR.

Having just been through this war on the RV-10 list, I had to dig up as
much as I could to sort out the differences.

The only additional tidbit that I heard the other day that I don't know
how true it is, is that the Apollo stuff may have less power but the
Garmin stuff requires more power to do equal work. That's only a side
comment, but I have no idea of it's factual-ness.

WOW! Great info! It had to take quite a bit of work to put all that
together. Thanks!

Doug,
It's a good chart, but like statistics, can also be misleading. In
short, the Pros and Cons are not weighted. It says that the 480 has 18
buttons but the 430 only has 12, hence the 430 is 50% simpler---not. My
original comment regarding the 480 being far and away superior to IFR
work stands. Entering airways, intersections and data into a flight
plan, be it new or edited, is a snap. Rarely do you have to enter much
of any letter or number designators--most are grabbed off the drop down
lists or the soft key choices, when then automatically tunes the radio,
VOR or enters the choice into the flight plan.
I the whole chart, this very important operating characteristic is given
a single line say the 'entering airways is easier in the 480'. That's
like saying the Atlantic is bigger than Lake Erie...it's true, but
sharply understates the difference. Other chart entries that are of
little significance where the 430 may be equal or even superior is given
the same weight at things that are actually important functionally. So
yes, the chart is useful, but only as a starting point, not a final
decision tool.
