VS all FM Transmitters like 
For all those cars without an MP3 player and just with a FM radio, it was a hard time to listen to favorite MP3 music. To add to this problem, there is no way to introduce an external auxillary since most models are factory preset. This was the problem I faced too.
Hence I decided to buy a FM transmitter which get input from an IPod and then broadcast in the FM transmission frequency that I set so that I can tune my car radio to this particular FM frequency. Ever since I started to think of which product to buy, mostly I saw complaints and concerns about the quality of audio that a FM transmitter can give. Many from Metro areas had comments that it was very hard to find a free FM frequency for them to tune it. Also in car movement sometimes the frequency gets jammed with some other local interference thus creating squeaky noises from speaker at times.
Then, I found this Sony cassette Adapter. Fortunately in my corolla I had a tape with the audio system. This cassette adapter has a auxillary input pin which you can plug in to your IPod (literally any audio device) and just insert this cassette in to the audio system as you would do for any other cassette and home audio system. Voila!!! The sound quality was great and I am now able to enjoy hours of my mp3 music from IPod without any interference during travel. This is much much cheaper than the FM transmitter and also does not require any batteries or power like FM transmitters.
I would recommend going for a cassette adapter if the car does have a tape ; else there is no other way than FM transmitter
