OK update, same thing with the car running. Auto detection does not work, same message, and manual doesn't do anything either. Fail Sauce.

I also figured out the admin part. Test the head, it said that its connected and communicating. IP is coo126 192.168.68.31. I also disconnected it, and reconnected successfully. So I don't think there is an issue with the gt1/DIS.

What should I try now? Should I bother disconnecting the battery and reconnecting it?
