    It is not at all clear what you are asking.

    Aux usually refers to an input and portable radios seldom have an aux input. Are you talking about the headphone output jack?

    And what is it you want to happen when a signal is seen on this jack. Switch on a Bluetooth transmitter perhaps?

    Okay. But you cannot get an output from the input jack! The only way to do this would be to wire into the switch that selects AUX as input on the radio. That may or may not be easy.

    Also, are you taking about a Bluetooth transmitter or receiver? I would guess receiver, which is plugged into the AUX jack and would receive music from some other device, playing it through the radio when you select AUX.

    Is that what you are trying to do?

    I am not trying to get output, i just need to know where can i connect relay to swich power 2 that is different source from the radio power 1,so the Bluetooth won't be turned on always. Thr second is correct, i want to play music from smartphone to radio when turned to aux

    Yes, you are trying to get an output. You are trying to get a signal out of the radio that that tells you when AUX is selected. But there is no such output from the radio. You would need a schematic of the radio to determine what was needed.
