駿河屋 -<中古>北米版 PLAYSTATION MOVE NAVIGATION CONTROLLER (国内版本体動作可)(プレイステーション3)
Sony Playstation Move Motion CECH-ZCM1U & Navigation Controller ZCS1U PS3 PS4 | eBay
Possible PS-Nav-Controller upgrade to make it trackable for a PC. I thought that since you can set a tracking light for the headset itself why not one for each Nav controllers? Hope
