I highly doubt that they would eliminate AM/FM radios from cars. I can see CDs leaving because they take a lot of space within the dash that could be better used, let alone the fact they have a moving part.

The circuitry needed to support radio isn't much and would most likely be integrated with other services into a simple chip set. Plus lets be frank, the youth today who don't find radio "hip" or whatnot aren't usually in position to buy new cars.
