FM Transmitter

• 1). Purchase an FM transmitter for your MP3 device. These are sold at most electronic stores and online retailers.

Tune to the matching station frequency on the car stereo and you will hear the output from your MP3 player. Remember to select an unused stereo channel to avoid outside interference.
