So offer to meet up and take back what belongs to you. Bust that mf'er upside the head as soon as you see him. It's the only thing a low life will understand.
If he had some sort of identifying markings to know 100% sure, it was his, don’t crack him at the meetup, put a non Apple tracker somewhere where he won’t see it, catch him at his home 20, and give religion to the entire family. I would want them to wonder who it is and which truck. And send a Christmas card with NSW pictures of the “conversion.”
