Re: FM transmitter or cassette kit for MP3?
Cassette adapter works better than FM transmitter. That what I have heard from most people. I have tried both myself too. The quality of music on FM Transmitter sucked big time. The cassette adapter is the closest thing you can get. But beware! you only want to get the one from Sony. I returned one that I bought from Radioshack and bought a Sony one from ebay for under $10.00. Its around $23 in the stores.
