In the following text I described how to connect normal audo device with mp3 player that consist USB slot for pendrive.
For a long time I wanted to add an mp3 function to my old mini – audio system. Device is so good that I rally want to keep it. So idea was to insert some mp3 player with low costs. Choice was a car transmitter mp3 USB with remote control

After I had dismantled transmitter I got 2 small electric boards. All you need to do is powered those boards by 12 direct current (also 9-15V works) and connect stereo signal to amplifier input

In case of working with car audio, you can simple plug to feeding – signal can be transmit thought FM tuner on frequency between 88,5-108 MHz. but to avoid any “noise” there will be better an electric connection by3 wires ( left channel, right channel, mass). Then good idea is to remove antenna to avoid emitting signal to far.

At my audio –tower I placed system in tuner casing, cause there are all signal inputs. Wires with stereo signal is soldered to CINCH slots.
As a feeding I choose rectifying diodes of inside power supply, that gives about 12V.
To make construction easier, and avoid unchangeable modifications I refuse of putting 4 outsides buttons and display of mp3 so controlling is only from remote. USB slot I got out through small gap in casing.
Of course you always can made buttons usb slot and display at front panel of audio system.
To have possibility of working with remote control, you need to unsolder infrared sensor from transmitter and get it out by 3 wires into front panel of audio system. At my I hide it after display glass.
