From reading the summary it appears that an SDR would be compliant, plus it wouldopen up the possibility of listening to many other things besides (for one, you wouldn't need a separate FM radio. For another, it could also receive weather data).
They're pretty cheap nowadays even for one-off consumer purchases. I imagine the cost would be minimal on an automaker's scale.
