I reply to the dealership as follows;
The media screen does look a little ‘odd’. I don’t see a TV option but I do see a ‘half a box’ which doesn’t look right. Maybe there is some way that the boxes are out of the right position – maybe a way to position this back on the screen. I will go and have a fiddle to see if it can be zoomed or dragged.
Photo attached… see the half box at the bottom.
Radio is obviously correct, USB has a USB stick plugged in – which works fine, Nexus 5x is my phone which has paired up fine, media library is empty – which is I believe correct, then that odd half box.
It will turn out that this was just slightly misleading as it is just the way the screen has an artificial ‘reflection’ in the graphics.
