Everyone else was doing it, so i figured why not?
I ran the power off the 12V adapter, which is switched by the ignition. Pulled the mute button through the gauges, built a mount which is run into the headliner to ensure the unit retains it's position.
You can see the unit from the outside if you look closely, a tint strip will soon cover it. I ensured that it sits lower than the front windshield defrost strips.
