Speaking only for myself, its pretty damm confusing exactly what would be
done with WAAS even if implemented. Garmins' other units that accept

WAAS is now implemented and IFR approved as of the past week.

If a receiver were approved for WAAS approaches, then TODAY you could use
VNAV/LNAV miniums on GPS RNAV approaches instead of LNAV minimums.
Presumably (though I am not certain) a VNAV/LNAV GPS RNAV approach would be
considered a precision approach. UPSAT's CNX80 web page touts the airports
you have access to today with WAAS; yet the version of the POH supplement
posted on their site says in the legal fineprint that precision approaches
are NOT permitted. So I am not certain if you can or cannot fly VNAV/LNAV
GPS approach mininums TODAY on a CNX-80.

I wouldn't be so certain of that. Today's VNAV minimums are predicated on
IFR-certified Baro VNAV equipment, not WAAS. WAAS approaches have yet to appear
from the FAA
