For road trips, we always just play mp3's off of our phone. (The car doesn't have aux in, so we actually use a FM transmitter dongle for the phone.)

(Stations generally have a genre of music they play, so they'll repeat the same ten songs of that genre.) But I agree that software defined radio would be an interesting function to have on a phone.
