7 Steps to Make Your MP3 Player Work with a Digital FM Transmitter

Have ever thought of enjoying your MP3 files while walking on the road? In fact you can play your MP3 files in the car by using a digital FM transmitter. The transmitter plugs into your MP3 player and transmits the files on your device through FM radio waves to the car's FM radio receiver. Here's how to use a digital FM transmitter with your MP3 player.

Step 1

Find out what kind of transmitter is compatible with your MP3 player. Your best bet is to find one that plugs into your player's audio output jack.

Step 2

Decide how complex you want your transmitter to be. Some transmitters broadcast at a preprogrammed frequency, while others allow you to change it. (Being able to change it gives you more flexibility in urban areas, where a preprogrammed frequency might be the same as or close to an existing station. This will cause interference.)

Step 3

Position your MP3 player close enough to the FM transmitter so that you can connect the two, but still control your MP3 player by hand.

Step 4

Position your FM transmitter close enough to the receiver (such as the car radio) so that the signal is clearly picked up by the transmitter.

Step 5

Tune your radio to the preprogrammed frequency, or the frequency you choose.

Step 6

Tune your transmitter to the same frequency (if it's not preprogrammed).

Step 7

Press "Play" on your MP3 player. Now your MP3 songs will play through the radio.
