So, plugged the dtuk box back in after having the car in for warranty work. Engine light came on and it felt sluggish. The box had come loose, so I turned it off and wwited. Plug the box back in and there doesn't appear to be any life about it, it flickers when connected but nothing else happens.
Holding + and - doesn't do anything.
Is the box now FUBAR?
I took it all out of the car and the lights went off. So the cars not broke.
Also appreciate I could ask dtuk, but it's 3rd hand at least by now.
Thanks in advance
