We expect to have a software update that makes the transponder fully compliant with the newest ADS-B rules by the middle of this year. The update will be part of a normal SkyView release that will update the transponder automatically.
The only GPS that will work to make you fully compliant with the rule is a Garmin 430W or 530W, and depending on the age of your 430W/530W you may need to send it in for a software upgrade, since the data required to meet the ADS-B rules was not put out in the original versions of the units.

So the Dynon GPS will not be supported to connect to the Dynon Transponder for ADS-B?

The Dynon GPS already hooks to the ADS-B transponder. The GPS goes in to the SkyView and the SkyView passes this to the transponder. This works today.
However, the Dynon GPS is not a TSO'd GPS, and the ADS-B mandate requires a WASS TSO'd GPS. Thus, if you have a TSO GPS, you hook that into the Transponder direct so that the data is never intercepted by a non-TSO device (SkyView). The ADS-B requirements need more data from the GPS than many devices output, so the only TSO'd GPS we know of that can meet the requirements today are the G430/530 (and some expensive standalone devices that cost as much or more than a 430).
We do report position over ADS-B using any GPS we have today, but this is broadcast as a "low integrity" GPS position and is only used for advisory purposes. This is quite useful today as it will let other planes see you and will let you receive ADS-B services, but by 2020 you will need a TSO'd GPS on board. Hopefully there will be a bounty of affordable devices in the next 9 years.

That it's TSO'd is only part of the equation. Even the 430W, with all of its continuous updates that make it such a compelling product for the IFR market, will need a software update (recently released, I think, but we've heard it's at least in the works) before it can output all of the right info so that an ADS-B out device like our transponders can consider it a high integrity enough source*.
So given the 480 is now pretty much an orphaned product, I would guess it won't be updated to support all of the right bits of data. That's really a better question for Garmin though.
*Our transponder will need update - date TBD - before it can both understand the new 430W data output and turn it into an ADS-B signal that meets the new FAA rules for ADS-B OUT.
