How to Hook Up a Cell Phone to a Car Stereo

By Stephen Lilley

If your cell phone has a portable media on it, you can connect it to the stereo in your car to listen to your music while you drive. You will still be able to send and receive calls, and will even be able to use your car speakers to listen to whoever is on the other end of the phone. The methods for hooking up a cell phone to a car stereo will be different depending on the type of car stereo that you have to work with.

Things You'll Need

  • Auxiliary Cable (optional)
  • FM Transmitter (optional)

Step 1

Examine the front panel of your car stereo. Look for a tiny, circular input that reads "AUX." This is an auxiliary input. If one of these inputs is present, continue to Step 2. If one is not present, skip to Step 3.

Step 2

Plug an auxiliary cable into the circular "AUX" input on your car stereo. Then, plug the other end of the same auxiliary cable into the headphone input on your cellular telephone. Any sounds that come from the cell phone will then be played over your car stereo as opposed to the cell phone speaker.

Step 3

Use an FM Transmitter. Simply plug the FM Transmitter into the headphone input on your cellular telephone. Then, use your car stereo FM radio to find a station that is completely static filled and is receiving no broadcasting signals. Tune your FM Transmitter to that same station, and any sounds that come from the cell phone will then be played over your car stereo as opposed to the cell phone speaker.
