The depth of the photo doesn't do it justice, you can also select from 15+ different display colors - I went with a hue that nearly matches the inside lighting at night. FM is going away in many countries in Europe for a digital system - DAB+ - so changing gives you more radio channels, better sound quality. Choice of head unit was to retain CD use (I have a lot), add Bluetooth and iPhone/iPod use.

I understand some comments, but road wheel selection if MUCH more personal than the head unit
