Mate, it might be easier to google whether it is safe plugging an output device (i.e. your screen) into an input RCA plug (i.e. source like a external DVD player)
My guess is it should be fine, just have a DVD playing on your car entertainment system and you'll know which one the output one is when a picture plays on the screen
All this is assuming it is via RCAs and if not, then identify the kinds of sockets they are (couldn't figure what else they'd be except maybe 9 pin DINs or S-Video) and see if it is safe doing the swapping stuff described above
Now that I'm in North America, I'm greatly concerned about raised pick-up trucks and owners of wedge shaped vehicles. Seriously, not only do you have to be concerned about one hitting you in an accident, they stand a good chance of driving over you at the same time!
