I thought the FAA approved the use of GPS for any NDB waypoint. A plane
without ADF can fly any ADF approach with a IFR approach certified GPS. GPS
waypoints can also be used in lue of ADF for missed approach holds, so you
can fly any approach that has "ADF required" without an ADF if you have an
IFR certified GPS.

Hello,

I read on the Garmin page that their 480 is Waas certified...so that
you can fly precision approaches without an ILS... what does this
mean exactly? If I'm coming into an airport with only an NDB
approach, can I use the 480's capabilites to fly a precision approach
and get down to a lower MDA/DH?


If the airport has only an NDB approach, how are you going to fly a GPS
approach of any sort?
