I have an android phone and I want to use the mp3 player on it in my car stereo. All I have in my car is the factory radio that came with it. There's no cassette deck or cd player or auxillary output or usb port in the car. It's just a simple old radio. I know that I could use an FM modulator, but a lot of people say that the sound quality sucks that way. I was curious if anyone knew any other way for me to do this. Any advice at all would be greatly appreciated.
