That however will need a “W” GPS to feed it the “certified” position. Presumably that would “just work” with a GTN later. And if Avidyne ever do the ADS-B IN on the TAS605 then that will also need a “W” GPS, for the same reason.
You’re probably ok, but there was an AD on the firmware in 2005. You should be on v3.03 or v3.06 or later.
Hmmm I wonder what this was about? I have never had ATC complain
I believe it fixed an issue with the GTX330 occasionally not replying to an interrogating TCAS system.

Why would ADS-B in need a WAAS position source?
One can see the certification reasoning (because the ADS-B IN is a certified box) but this is nuts in reality, and IMHO if you took the data out of a KLN94 and used a protocol converter to fake a “W” GPS data stream, it would be just as good for traffic awareness…

Ok interesting. I suppose the argument is that to correctly display WAAS accuracy traffic, your position must be similarly accurate.
Making the bet that an ADS-B out mandate would come at some point + I want the ADS-B in aircraft to see me, I jumped straight to the 345. Might as well spare yourself the install cost.
Did you install the WAAS GPS antenna which the GTX345 needs (if using its internal GPS)?
If I did that, and later put in the GTN (or 2×GTN) I would (due to not wishing to have more antennae than the GCHQ) have to disable the 345’s GPS and re-use that antenna for a GTN, and anyway the 345’s GPS would be irrelevant.
IMHO an ADS-B mandate of any sort of < 5700kg IFR GA is years and years away. But for sure one would not want to preclude it by doing something stupid.
Basically, on a TB20, anything is fairly easy except for the centre stack which is pretty hard.
Thinking about it more, on my plane, the only way I will be able to do ADS-B OUT is with a GTX345 (or a similar box) – because the TAS605 will never do ADS-B OUT. So, since I am not likely to be removing the TAS605, putting in the 345 is not likely to be wasted, ever.
We did this here to some extent.

Couldn’t a 345 share the GPS position with the GTN.
But I am with Denopa. If doing now I would fit a 345 not a 330ES.
