There is no change in the airspace requiring a transponder. However,
there is a new requirement for ADS-B equipment. There are two ways to
comply. You can either get a Mode S transponder that has software to
give the data output needed, or you can get a UAT unit that is tied to
your Mode C transponder. Either variety has to have either an internal
GPS that meets requirements, or be connected to a certified WAAS IFR
GPS. There are a number of sources for the information, including
manufacturers. However, a lot will confuse the issue.
The requirements are only to transmit the required data stream.
There are no reception requirements, but that is another entire ball of
wax, as to what traffic and weather you do or don't receive, and how you
display it in the cockpit. Very useful, but not required.

I've not kept current with the requirements
or all the features/options in the transponder
world. I've posted this question to the
AeroElectric-List. There are folks on tha
service with a great deal more knowledge on
this topic.

Last I heard the 430/530 software had been patched, as it was required
for all transponders, not just non-Garmin. Garmin had to fix the data
stream output that wasn't 100% compliant. When they did that it became
ADSB+ output, and both the GPS and the transponder had to have software
updates to use that specific format. I'm using a GTN650 with a
Trig/Dynon transponder, and I had to update both. My avionics shop got
the update from Garmin.

You are correct wit is that h regaeds to the Garmin transponders. The
information that I have from Trig i and a Avidyne 540Ts that Garmin
430w/530w are not approved as the gps source unless they are updated per
Garmin. The software update is not currently available and may never
become available. My work around is a Trig/Dynon 261 mode s and an
Avidyne 540T all certified and approved. Only draw back was the price.

I don't believe that statement is true, as both of these WAAS-equipped
devices ARE approved GPS sources for any of the Garmin ADS-B Out
transponders. I had a GTX-330 upgraded to 330ES (around $1200) by
Garmin, then connected to my 430W (cost about $600 for the shop to
rewire to add the GPS connector to the 330ES). This was fully approved,
and passed all the FAA's ADS-B Out testing. And a friend who had a 530W
and 330 did the same with his plane, and likewise passed the FAA
testing. I also know of several people who have upgraded to Garmin 335
and 345 transponders and used their 430W/530W as the GPS-WAAS source for
their ADS-B installations.
One possible source of confusion might be that the older non-WAAS
4XX/5XX models are NOT approved because they lack the WAAS GPS
capability. A non-WAAS 430 (or 530) would need to be upgraded to 430W
(or 530W) to add the WAAS capability. This can only be done by Garmin,
and I think they charge something like $3,000 (IIRC) to upgrade the
units.
But the bigger issue for Garmin 430W/530W owners is working with
non-Garmin ADS-B transponders... I believe the issue is that (at least
at one time) the Trig ADS-B transponder (which is re-sold by Avidyne and
several others under their own company name) was NOT certified with the
430W/530W. Obviously, Garmin had no interest in pursuing certification
with someone else's equipment, and although I think Trig eventually
certified their own proprietary brand unit with the 430W/530W,
apparently the other companies that were re-selling the Trig unit did
not pursue certification with the Garmin either. But check into it,
because this stuff changes very rapidly.
