Help w/2 TV install with diff cable type

I have a Chrysler T&C 2003. I have a dealer installed rear dvd with a flip down LCD. Well, my problem is a just bought a cheap LCD screen from Pyramid ($90 US).........I also bought a  4 channel video amp ( XOvision AMP-7). The problem is the monitor that the dealer install has a data type cable intead of RCA........the video amp has no connection for this type of cable. What can i do? Also the Pyramid LCD has a female end rca........I need to convert this to a male end rca in order to connect it to the video amp. Can someone give me some advice?Rocky

Data Type Cable? What do you mean, like a BNC connector (Push down and turn to lock?)? When you say DATA CABLE, I am interpreting it as that the signal going to the dealer installed screen is a DIGITAL signal from the DVD player (like HDTV component level), converted to analog by the TV. That is pretty rare in any case for a VAN, I hope you only mean the CONNECTOR is just different. OR is it like a VGA monitor connector? That would also be a digital picture, and rare in AUTO use. The DVD player should still have a standard RCA VIDEO OUT plug that you can use in your distribution amp. If you mean a BNC type connector, The video signal should be the same as with the RCA, just use an adapter if that is the case (BNC to RCA). In fact, Time Laps VCRs come with BNC to RCA adapters in them for the off-the-shelf video security packages. The dadapters are also available at Radio Shack (BNC MALE to RCA MALE). I use them all the time in Video Security Apps.
