More and more vehicles feature a dashboard space for a 7-inch or 8-inch screen, however behind the screen there is no space to fit a full 2DIN product. The new SMART is for example one of the vehicles with such dashboard design. Alpine designed the X803D-U to overcome this problem by putting a 1DIN chassis in the back of a 8-inch screen. With a car specific Alpine installation kit you can achieve a perfect installation and original manufacturer look.
