I'll show you guys some pics of my setup. I understand it will not be the best for some people, but for me it's perfect. I took the power from the overhead panel so my RD is always powered, but a switch in the middle makes it easy to manage the power of the unit (switch located in the glasses box in the overhead). I received my new RD today so I had to do this asap.
Last pic is one from my previous car, a B7 2008 RS4... Had so much fun in this car, but had to change for the new look!
I'll show you my LI DUAL install later one.
