I swapped my 430 for the 430W unit a few weeks back and indeed the
WAAS unit uses a 16 BM data card (I don't know the size of the terrain
card yet).

The card requires the USB adapter for programming and it takes about
30-40 minutes to burn a new one.

The terrain cards are only available from Garmin, and they have a
different hardware device for programming them. Garmin wants about $99
for that unit. The terrain updates are $35 for a single update and I
believe it's $410 for the annual subscription.

As for the Jeppesen update, the can cancel your non-waas remaining
time and credit it to the new WAAS subscription. Very helpful folks
there.

Did anyone come to a conclusion yet on the question of whether or not the
PCI adapter will still work to update the cards for the 430/530 waas units ?

Is it also confirmed that it uses a new card ?

Jeppesens web site is terrible ! try a search on the key word waas and it
comes up with zero hits.
Also there navdata pages do not mention anything about waas.

Thanks in advance...
