I bought this old Jag for a project. It has 9000 Europe Audiophile (premium) radio and it was totally locked. I read about this problem all around internet and found a solution. There is a guy in Turkey who sells a tool that can fix Ford radio locked 13 problems. He was not sure if it works with my unit but I took the risk and bought it 'cause the connectors are similar than in Ford 5000/6000/7000 units. And it worked. Took several tries but I finally managed to unlock it.
