Hi Dan

I think you might be confusing the Trig TN70 and TN72 that Mike mentioned.

The TN70 is an existing ~$3k TSO-C145c GPS source from Trig that has been available for quite a while. It's a rebranded NexNav Mini. I had suspected the TN72 will be a rebranded NexNav Micro-i. Early photos from UK TABS trials showed a TN72 in NexNav looking packaging that looked like a Micro-i. Accord (the maker of NexNav GPS) was acquired by Aspen in 2015 and it's going to be interesting what happens there long term, especially with competition with Garmin. Accord makes nice stuff but they seemed to often announce new things quite early for the OEM market. If the low-cost TN72 is TSO-C145c approved it would replace the $3k TN70... which has me a bit suspicious of Trig announcing this early at Oshkosh (regardless of what staff there told Mike). If it's based on the Micro-i, then given what Accord has said about the Micro-i in the past it likely would not be TSO-C145c approved and would be for experimental aircraft only or TABS if TABS ever happens. If could be based on something entirely different, we'll have to wait and see. Again if it is TSO-C145c approved at that price point that is a really dramatic change, but right now that price point is where competing "meets requirements of..." GPS sources like the Garmin GPS 20A are priced (and Trig has no OEM/rebadged product to match today).

What they are telling you here about a TN70 install is not really different than what I said earlier. With an TSO-C145c approved GPS source and an existing AML STC for use with the Trig TT-22 that forms a basis for a field approval/337 install even for aircraft not on the AML list. There are other Trig/Peregrine STCs for third party GPS sources as well but you might as well use the TN70 today. As for using their maintenance network good point there, I'd missed that before although Trig say the same thing on their web site. Especially for glider installs by a glider A&P I hope/expect they would be flexible here.

And you likely know the relationships here but Peregrine Aero is essentially a consulting company that Trig paid to develop the AML STCs for the ADS-B Out installs of it's product. They seemed to do a good job getting stuff done.

I just heard from Peregrine Aero regarding installation of a TN70 to go
with my TT22. This part of what they told me:

The recent FAA policy on field approval installations makes it much more practical for the repair stations within the Trig dealership network to accomplish our STC on models that are not currently included on the AML. The TT22 and the TN 70 are an approved equipment pair under our STC (SA00756DE), so the repair stations within the Trig dealer network have the ability to complete this installation as an approved alteration so long as the equipment Is installed per the instructions provided by our STC and per the FAA policy on ADS-B installations.

Now to wait and see when the TN70 becomes available. I hope it's as
simple as that...
