Hello

As mentioned above, my question is about how to convert the wireless transmission of the MP3 Player FM Transmitters to wired to car radio, I want to remove the broadcast via fm waves and send sound through wires to the radio using an aux input, knowing that the mp3 Player FM Transmitter does not have an aux output

What is required, then, is the following:

- Add aux output for MP3 Player FM Transmitters

- Disable the device's wireless transmission feature and send data from aux output of the device to the aux input of the radio.

These are the pictures of the device

Even with a schematic of the device and a lot of experience, your chances of succeeding are minimal. It would be far simpler to purchase a MP3 player with audio output. Here is one from AliExpress:

It costs $1.05 US and all it needs is a couple of push buttons, 12V to USB 1A charger for power and an audio cable to connect it to your sound system. Here is the datasheet with application notes:

Unfortunately the linked unit above is Mono, not Stereo.

Get a new Head-Unit, all the new ones come with a USB Jack right on the front.
