aftermarket lcd...please help me out!
 

I bought 2007 pac touring with factory installed cd/dvd player and 6-disc dvd changer.
It didn't come with screen.
Ialready purchased aftermarket 10.4" stand-alone lcd screen through the internet.
Lcd displays " No Signal" when I put the rca cables(two for audio & one for video) into the AV jacks(3 holes)located in front of dvd unit.(single cd/dvd player also has one)
Sound comes out through the front speakers but no screen working when I insert dvd title and play it.
Someone said I needtobuy chrysler dvd remote to get it worked.
Isthat true?
I don't have to take off the trims and splice into the cables toget the working screen?
I'm stuck...
Please help me!
My kid's been waiting to get "Thomas and Elmo" while on board.
Thank you.
