Wow...had no idea about the lack of AM radio. That's a huge kick in the sack. I listen to sports talk radio or games pretty much 75% of the time in my car. This is a pretty massive disappointment for me that I can no longer listen to White Sox, Blackhawks, or Notre Dame games in my car, or listen to my daily sports talk radio.
A lot of radio stations can be found on Tune In which is built into the current cars (and I assume will be in the 3). Take a look and see if your stations are listed. Sports radio | Listen Online Free | TuneIn
