Looking for some help I fitted video head rests to my wife's Q7. Trying to pick up a switched live, the problem I'm having is getting the right wire. I connected in to terminal 15 but the problem is once I turn off the ignition it kills the power to the head rests. When you put the key in the ignition the radio turns on and the steering lock comes off. This is the line/wire that I would really like to connect in to but I can't find it??? Is the radio and steering lock controlled by tha canbus system?
