This GTX 327 Transponder is in excellent condition! It was bought for an upgrade to a Mooney back in 2010, and we just started the project last May. We’re now doing a completely different panel, with a G3X, GTX 345, etc. It has been in a climate controlled closet ever since. Comes with everything shown; unit, rack, back plate, connector.

IF you want it to come tagged with a fresh 91.413 check so you can install it and be good to go for two years, I can do that for an extra $100. If you’re doing it as part of an upgrade and will be doing that anyway, then there’s really no need.
