Install a Wireless and Cable Free FM Transmitter in a Car

FM Transmitters were developed to hear music in a car without operating a CD player. Owners of vintage cars can hear music from MP3 data without using an MP3 player, only from an USB stick or SD-card.

Steps

  1. Understand that the transmitter has a weak transmission performance with a range of only one yard. This is the reason for allowing the use in many countries. It will be operated by the car plug-in (12 V tension on board).
  2. Look for a frequency on your car radio between 87,4  and 108 MHz, where no other radio stations are sending and disturbing your own music.
  3. Set up this frequency on your FM transmitter (see the manual) after putting it into the 12 V plug-in.
  4. Connect your MP3 source (it may be an USB stick, a SD card or by cable a MP3 player, all loaded up with your music).
  5. Make sure the music is good-quality. The functions of the car radio (balance, loudness, treble, bass) can be used as usual.
  6. In case of quality loss of the sound change the frequency of the transmitter and the radio.
  7. Keep in mind that a frequency change may be necessary more often, when travelling long distance. This is especially the case when many radio stations use frequencies in a very small range and a great signal performance.
  8. When leaving the car, disconnect the transmitter from the car electric, as it can empty your car battery.
  9. Keep in mind that FM car radios, built in the 1950s, can receive the signal, as it acts like a normal radio station. Be mindful of the tension on board. Many elder cars operate with 6 V. In this case you must use a voltage converter from 6 to 12 Volts.

Tips

  • Some countries do not allow to operate such transmitters. Get information about the legal situation before operating this.
  • This transmitter can be used as a music player outside a car.You need : a transistor radio with FM range instead of a car radioa 12 V Car charger (110 - 240 V to 12 V transformator)Find a free frequency range and use the same one for radio and transmitter.

Warnings

  • Mind the correct tension for the installation.
  • Keep away from children.
  • Remove the transmitter from tension if it becomes too warm to avoid fire.
  • For any further information see the manufacturer's manual (radio, car and transmitter)
  • If the fuse breaks down , find the reason for the failure and n e v e r replace the fuse by a"stronger" one
  • Always monitor the operating temperature, especially at warm weather.
