Possible to install Factroy overhead dvd screen in my 08

[muzbomb]

Hey guys I am new to the forum!!! I have a 2008 Tahoe LT. It doesn't have the nav radio screen up front but it has the 6 CD media player up front. So I found a rear overhead DVD screen unit that I would like to put in my Tahoe for the kids. Just wondering if I buy the screen will it just install and plug right into the factory radio? Will I need a wire harness to go from the radio to the screen?? How does this all work my would really like to put this in for my kids. Thanks

Ok so I just bought a Factory navi media player for up front, so if I buy this rear overhead dvd unit now is it a basic just wire harness plug and play into the factory navi indash system? Thank
