You may have reduced your chances for an answer when you asked,
"Does anyone know...".
Yes, the intent is for the 430/530 units to satisfy TSO-C146a eventually,
but we'll *know* it when we see it happen.
Let's hope the schedule doesn't slip any further. :-/

Does anyone know if the upcoming (someday) WAAS upgrade to the GARMIN
430/530 will make it TSO 146a compliant unit?

Most GPS navigators are TSO C 129 except for the CNS 480.

129 units are considered secondary navigation devices.

The consequence is that you must have VHF navigation for
an alternate and pick an alternate that is not GPS-only for
approaches. BTW, that is why you still have to do your vor
checks even tho you nav by GPS everywhere.

Donno about that missed approach business... haven't heard that
one.
