We are all waiting for the 430 units to start shipping or upgrading.

A couple of months ago I called Garmin and asked them to speculate on the
availability of the WAAS upgrade for the GNS-430 and a tech told me June or
July 2005 (in the US).

My local avionics shop claimed that they had heard this date, too.

FWIW...

I wouldn't hold my breath.

It seems to me that the reason they bought out Apollo/UPSAT in the
first place was so that they wouldn't have to really tackle the problem
of providing an upgrade for the 430/530. They were months behind on
that schedule a year and a half ago. The last thing they want to do is
to resurrect that old chestnut. They want to sell 480's now and you can
bet dollars to doughnuts that they don't want to compete with
themselves.

The GNS-480 a superior product anyway. Maybe they will take 430/530's
in trade. :-)
