So I only use my car radio with my ipod tuner, but it gets too much static when I'm in town so I mostly just use it on the interstate. That means that when I get in the car, if I don't have a CD in I get some local radio station. The last few times I got in my car I have heard this preacher preaching the bits of the bible about how women should serve their men and remain silent in the church and all those things MOST modern Christians ignore now. It wasn't just once, this has been several days in a row he's talked about this subject and it cracks me up every morning.
Right now my radio doesn't function at all(which makes my drive to school that much more boring), but, before it did, I would plug in my ipod to the sound system to listen to with a cassette adapter. Do you have a cassette player? Chances are that you don't, but I used the ipod tuner which players over an empty radio frequency and getting it to work was pretty bogus - and I live in a highly rural area at that. But the casette player is cheaper and works pretty well, although some would argue that the quality may be compromised, but I dont notice any actual difference.
P.S. We'd all be in a world of trouble if Christians followed every bit of their doctrine literally.
