The Digital Age
Radio experimenters begin to use computers with audio cards to process radio signals, and the first digital transmissions begin to be broadcasted. -

All of this history leads to today. The Radio can be accessed through any mobile device and in any car.

Future Prediction
I would predict that radios in cars will evolve from being touchscreen and bluetooth. My prediction is that it all possibly become voice activated without flaws, and/or it becomes a 3-D visual.
