We are going to Maine in a few weeks and my wife's radio in her car sucks. The CD player is broken and/or dying. I'm going to go nuts listening to the radio for 12 hours. I was considering getting a radio connector for my iPhone, but I'm not sure exactly what FM receiver thingy I need to get to connect my iPhone into the car. Basically I want to get something that I can plug my iPhone into that has an FM frequency so I can listen to my music on my iPhone. Any ideas? Oh and I don't want to spend $200 dollars either. Something $50 or under should be fine.
