Non-TSO'd Equipment for 415-C as Legacy LSA

The avionics shop signed off on it.

George, Did your IA sign-off on the installation?

We have the GTR200 installed!! Great radio.

My Alon had the GTR200 installed before I bought it.

I ran across this article (below) discussing the Garmin 200 as authorized for Legacy LSAs. Does anyone have an informed opinion about this issue?

Garmin’s standalone comm transceiver is the GTR 200 series, which includes the TSO-certified GTR 225 and GTR 225B (Bluetooth) models. It’s up to your installer to figure out if your aircraft requires the TSO version. LSAs—both legacy and newer ones—don’t require TSO’d gear. And while Garmin doesn’t advertise it (and markets the non-TSO’d GTR 200 and Bluetooth-equipped GTR 200B to the LSA and experimental market), we’ve heard of plenty of installers who retrofit the PMA’d version of Garmin’s GTR 200 into certified aircraft, with appropriate signoffs. This PMA version is intended for installations in Garmin’s G3X Touch integrated avionics suite, but it can work as a standalone, too. Again, talk to your installer about the legalities.
