The Comsoon J22 bluetooth adapter is a unit which allows your phone to connect to bluetooth, and provides a line-out to connect to a stereo or Aux IN in your car radio.

In this case, I'm using it in a 1986 Corvette with a Pioneer radio which has an aux in. This bracket attaches to the lower left of the center console bezel. Remove the existing screw and put in a pan head #8 screw of appropriate length (I believe I used a 1.5" screw).

The bracket allows space for the headphone cable or connector and the usb cable.
