I contacted Garmin's customer service, and below is the reply
that I got regarding when WAAS will be available as an upgrade
for the GNS 430/530:

-------------------------------------------------
The WAAS upgrade will not be available till the last quarter of 2006. But
to lock in the $1500.00 price you need to contact your Garmin avionics
dealer before August and make arrangements.

According to Garmin's product literature, the GNS 430 and 530 are
"WAAS-upgradeable", yet there is no information as to when this
upgrade might be available. Does anyone have any other information
on this?
