When I connect my phone, there is a nice music app for me to access everything on my phone. Unfortunately, the only way I can find to access my car FM/AM radio is to disconnect my phone (and any maps that may be running) and then find the station I want to listen to and plug it back in.

I don't see any way to get to the car stereo through car play. This is a major first world problem that must be rectified since I don't listen to internet radio very often.
