How to Hook Up an MP3 Player to a Car Stereo

Play an MP3 player through your car stereo with an adapter or transmitter.

One popular way to hook up an MP3 player to a car stereo is to use a cassette-tape adapter, similar to the ones used to play a CD player through a car stereo. Another way is to use an FM-transmitter device to broadcast the MP3 player's signal to the car stereo's radio receiver.

Things You'll Need

• Cassette adapter
• FM transmitter

Instructions

Cassette Adapter

1. Connect the 1/8-inch output from the cassette-adapter unit into the MP3 player's headphone or line-out jack.

2. Push the cassette-tape part of the adapter into the car stereo's cassette-tape deck.

3. Turn on the MP3 player. You will now hear it through the car speakers.

FM Transmitter

1. Plug the FM-transmitter device into the MP3 player.

2. Set the frequency at which to broadcast sound from the MP3 player. Find a frequency that is not currently being used in the area, usually around the low frequencies, such as 87.5.

3. Turn on the car stereo's radio and set the station on the same frequency as the FM transmitter. Turn on the MP3 player and play a song to hear it broadcast through the car stereo speakers.
