Working Garmin GTX330ES ADS-B out transponder. Installed on 05/01/2020 - just removed for GTN750xi upgrade. Being sold in as-is condition. Was working fine when removed by Garmin authorized dealer.
Shipping only to lower 48 states. Will combine shipping costs if you also buy my GNS430W (see other listing). Will refund shipping charges for local pickup. No reserve once opening bid is met. Thank you and good luck.
