Not very good pics but you get the idea of what the DAB aerial looks like and how I've ran it
Up the door pillar and into the headlining
Out of the headlining in the centre of the windscreen (above the rear view mirror)
Its a small black plastic thing, about an inch wide with 2 long clear strips with a wire inside from each end
Can't see it at all when driving.
I have also moved the headunit down to right above the climate control and moved the holder part up to remove the gap that was left.
