I know this is a long shot, but just In case anyone has a surplus GNX375 because they are planning to switch over to an integrated Axis with certified IFR WAAS built in, let me know. I know it isn't the same thing, as the Axis doesn't have a transponder, or ADSB, but just shouting out here. I need a new ADSB-In solution because the Axis doesn't support my GDL39 (which is for sale). If this happens, I would also have a uAvionics Tail Beacon ADSB Out system for sale. Aircraft Spruce lists the experimental GNX375 for $8,075, so I'd be looking to save some $ especially if it is out of warranty.
