This is a used John Deere Starfire 3000 receiver with SF1 SF2 and RTK activations/unlocks. It does not include a RTK radio. It has been tested and works as it should. Receive has mandatory update already on it. Has only 5101 hours on it. Will work with John Deere Greenstar displays. Very nice unit and ready to go! Please send a message if you have questions.
