If you're asking about the Kinivo, it's a single master controller button that attaches via adhesive to the dash. I have mine positioned near the Start button and it blends right in. A very thin wire is then fished into dash/console seams and to the back of the center console. One tip goes into the power port and the other tip goes into the AUX port. After initial pairing with my phone, connection to my phone happens automagically every time I open the door and the power port comes to life.
That is actually the only minor complaint I have-- when I'm working out in the garage I usually have music playing from my phone to a portable BT speaker. If I open the Landy's door, the Kinivo grabs the connection. The upside is that 99% of the time I want that to happen so I can't fault the device for being tenacious. Hope that answered the question.
