Installed my kit today. SO happy with it! Everything looks and sounds great. I'm not sure if sebastian initially was planning on putting the controller in the cigarette lighter, but it fits perfectly and is 100% hideable and looks like it came that way stock!

I put it right next to the Parrot bluetooth controller and tapped off the power that would have been going to it for my iphone aux/power-in-one connector.
