I am selling my GTX335. This unit worked when removed in July. It has no cosmetic blemishes. Tray and miscellaneous hardware included. Asking $2,400 shipped standard ground in USA.
This Mode S transponder provides a cost-effective means to comply with ADS-B out. This unit does not have a built-in WAAS source and will need this data from a WAAS GPS when installed. If your plane already has WAAS, this offers an economical upgrade path for ADS-B.
Garmin stickers this for $2,995. Technical and pricing data is available on their website:
