Garmin GTX 327 - Removed for Avionics Upgrade. Working great when removed. Confirmed with IFR6000 test set prior to posting listing. Just needs a new home so it doesn't continue to gather dust. Unit comes with Xpdr p/n 011-00490-00, installation tray, and backplate. Backplate connector currently is currently pinned for power/ground/test mode, but has all the remaining sockets open and ready for your installation. As it's removed from an aircraft for upgrade, there is no 8130-3.
