Hey, i just bought a P56038629AE deck out of from what i can tell a 2005 caravan, and i was just wondering if i could use this in my 2005 pacifica

i have cd player with cassete, + a 6 disc dvd changer underneath it that runs through the speakers, and the picture back to a head unit in the roof

i'm just wondering if i could put this deck i picked up in my pacifica, and have it for a 2nd screen, hook up the nav, and still not lose fuction of the screen in the back and my disc changer and sound through the speakers

if i was to lose the disc changer it wouldn't be the hugest problem, i would just want to make sure that the screen in the back would still play what i put in this unit with sound and everything

thanks
