No power to head unit

Hi got a problem with my stereo fitted the D4 screen a while ago but had poor reception so decided to change the fakra cables as the splitter was wrong so changed them around and now i have no sound no sat nav nothing not even the red light on the most so i assume i have blown a fuse.Is the smaller block to the rear of the head unit the power supply to it as i dont have any power there with the unit switched on/car running but have some power to the other block
thanks for any help Discovery 3 se gone
