Why my car FM Transmitter function is so noisy?
FM Transmitter transmits the FM band in 5 meters.
We know the FM radio station is a very wide range, if we set the same band with the radio station, our signal will affect a lot.
So we can follow the steps as below,
1.We adjust our car FM to the band without the radio station, like 108.0MHz.
2.We change our device FM band to the same band with car FM -108.0MHz.
3.We can play music via TF card or Bluetooth, check the quality of sound.
When playing music, get an incoming call, why the sound volume becomes louder or lower after answering it?
Because the calling volume is controlled by the ” Calls ” and music volume is controlled by ” Media ” in your phone volume settings.
So you can modify the settings on your phone to let the sound more comfortable.
