I was wondering what would be better for watching movie's in the car and having a back-up camera. I see alot of people are putting pioneer AVIC units and then some people using the stock navigation screens to watch tv and to use a back-up camera ( I have the stock nava) but which one of this has the better screen quality and has better advantage then the other one ???

Thanks if you can help.

 

So now can tell me what would be better to get. A in dash DD unit or get stuff so you can watch tv on the Navagation screen ???
