When you say "upgrade," do you mean from a 430 to 430W?

Or, do you mean from one 430W software version to a later version?

I ask, because the conversion of a 430 to a 430W represented a major
hardware change.

Chuck,

If you don't have any of the problems outline in the SB and don't have a
GDL69, the next most important benefit of the software upgrade is that the
GPS obtains "sole means of navigation" status. This means that you can use
numerous airports as an alternate that are unable to be used otherwise.
Most airports with an RNAV (GPS) Rwy xx approach that also have an ASOS for
weather may be filed as an alternate. Approach charts with the reverse A
symbol (white A on black triangle background) that don't have NA after the
symbol, will list the requirements in the special alternate minimums section
of the NOAA charts.
