I have an old work car ('04 Intrepid) and I'd like to connect my MP3 device to the car stereo so I can listen to Podcasts. However, since it is an old work car I don't necessarily want to spend a ton of money. I am not against MacGuyver-ey solutions, either (within reason).
I've tried an FM transmitter and it didn't work very well. There are no auxiliary inputs, and no tape deck.
I'd like to try to keep it at about the $50 price range (if possible). I am not a mechanic, but I do have PC repair experience so it's not beyond the realm of possibility for me to do some work myself.
