I think that in configuration in "Dashbord" or "Interior" category in every car there should be a slot for radio type (like in Sunburst or D and H-Series currently). We could insert different type of aftermarket 1- or/and 2DIN radios, tape decks, CD/MD players, multimedia stations, nav units etc. I don't even talk about them working, just for sheer looks. Also it'd be very nice if the units with foldable screens actually folded, when we turn on/off the car
