Connecting a DVD player to a Navi, help Options

[JoKeRkId613]

My bro has a tc but the answer would be exactly the same for the celi. so if that would remove my post then lets say the navi is in my celi. ok, its a pioneer d1 sum crap. the double din navi that doesnt play dvds. lol. so he got an external dvd player that he was going to put in the glove and connect it to the navi's a/v inputs. so the thing im trying to figure out is the power to the dvd. it comes with a dc adapter thing. so what i did was connect the dc plug to the cig lighter wires. i took the dc plug apart and hooked the yellow wire to the cig lighter's white-black stripe wire and the black wire from the dc plug to the black wire on the cig lighter. the cig lighter, to my understanding SHOULD be getting 12V constantly. The dvd wouldn't power up but you can hear some weird sound like it's trying to play the dvd and when you unhook the video output cable from the dvd player, you can see some white lines on the navi screen. so i KNOW it was getting SOME power. Just not enough to get it to power up fully. Somehow the dvd player fried and started smoking so it dont work no more. so im telling my bro to get a battery powered dvd so we dont have to mess with that stuff. lol. im not sure if we can find one thats battery powered tho so does anyone know how to hook up a dc adapter to the car? what's the best source? and how would you go about connecting the dc power adapter if it's a plug at the end with 2 metal prongs? i guess this would be hooked up the same way as the power plug for a ps2 or something? but i dont know how that works so can someone fill me in? thanks.
