Phone, Has anyone seen this before?

Would anyone know how this functions or if it does at all? I have hooked up my phone through the axillary jack and can hear phone conversations through the stereo. I still need to hold the phone for the microphone.
I have no bluetooth or phone button on the steering wheel. I bought the truck used and it didn't come with a owner's manual.

 

I think the govt is spying on you

 

It's an aftermarket mic. If the steroid isn't stock then it would be through the aftermarket stereo. Using aux wont activate it but USB might

 

Stock radio. No USB. I guess I'll have to put a bunch of lights in to use the switch spot

 

Random shot in the dark - any chance it's your cable from phone to Aux?
I had a usb plug for the power port, whenever I used it I lost radio signal. Unplug it & radio was fine. New plug & no interference.
I wonder if your cable is some sort of cheaper 1 function cable v. a 2 function cable - if such a thing even exists.
Anyway a thought. Good Luck.
