Suggest you go to the Garmin website, where you will find that the 430
and 530 ARE WAAS enabled. Even the cheap Garmin yellow etrex on the
shelves today (not the early ones) is WAAS enabled. It would in your
words be quite an omission for any NEW GPS unit to not be WAAS enabled,
though I certainly don't know that ALL of them are.

nothing about WAAS, which would be quite an omission if they supported
it.
