Replacing headliner on 06 M45 and adding rear DVD system.

[Alfa95]

Hi everyone. Recently I started seeing water in the rear passenger floor and thought my kids had spilled a sippy cup. Ended up being that the passenger side sunroof drain was leaking where the metal rail and plastic drain tube meet. My mechanic sealed it up with silicone and no more issues. About 2 weeks later, where he had moved around the headliner it started separating. Now the whole headliner fell down all the way to the back of the sunroof. I work at Tire Kingdom and can get the headliner from Infiniti for our cost which is about $530.

My question is the following. I found a used headliner assembly for $350 but it's for the model that has rear DVD. What else do I need to add the rear DVD? My car is a 2006 Sport M45. It has the DVD player in the middle armrest and plays movies while parked to the front display. Apart from the headliner, I saw there is a DVD bracket that goes on the roof, I found the roof DVD system that is motorized for about $150. What harness do I need and where does it go connected? What else is needed? Thanks in advance.

Any decent sunroof installation shop can re-wrap your stock headliner for a fair amount less than buying a new one. Food for thought.
