I have a brand new in the box GTX 335 transponder. I received it with an aircraft I purchased but I am going a different route for ADS-B. This is a Mode S transponder with ADS-B IN only. This will get you compliant with current ADS-B requirements.
The kit includes everything you need to install including tray, antenna, alt encoder and connector kit. See pictures for contents. Since this is brand new, I'm not very flexible on the price. This retails for $3195 plus tax and shipping.
Email me with contact information and I will get back to you ASAP. Local in-person cash sales only. Thanks for looking!
