i had that happen on a unit i installed once, i just pulled the mute wire out of the harness and it fixed it, i dont remeber if that unit has a mute wire, but if it does try that to see.

yeah i called a friend of mine and he came over I wasn't entirely sure that this wire needed to go to that spot and i snipped it turned it on and now works just fine lol. but now I cant seem to get it to play the video of dvds even when i'm parked i even tried sending 12 volts to the wire at all times and it still wont. so now i'm stumped again!

hook up with "parking brake" wire, should be light green on the unit i believe

i did that but its not doing anything, i hooked up the light green wire to 12 volts, even did it with a switch still nothing

The parking brake switch is a grounding switch. Connecting the wire to the switch provides ground (not 12V) when the parking brake is engaged.

If you continue to just randomly feed 12V power to wires for testing then you're going to end up with a fried head unit.

just a normal body ground should do the trick

use a switch, with on eend grounded--everytime you turn off the car, you will need to flip the switch to "reset" the parking brake input.
