The only way that would happen is if your pink wire is still somehow connected to the e-brake. You need to completely remove this wire from anything and only connect it to ground.
Earth the cable to the back of the stereo casing using a screw or insulation tape, it fools the stereo into thinking the e-brake is on and allows you to watch DVDs on the move. Just use with caution.
Also Disconnect all the speakers from the unit. Be sure to mark which wires go connected together. Connect each speaker one at a time to see if you get sound. Once you connect one speaker, see if you get sound. Then disconnect and try the next one. If you notice that by having only one speaker connected at a time, then there is a short in one of the speakers, see which one does not work. If none of the speakers work, then you may want to try to see if you can connect an external amplifier to it.

One more thing if the parking brake wire is connected or not… hook it up with any metallic ground under the dashboard but that can easily be bypassed by wiring the pink parking brake wire into your stereo ground wire.

My screen. On my valor is not working at all can not see anything , but radio works fine. What is wrong please help

  • If you haven't found the answer (or your like me and you found a post because you were looking for the same answer)...
  • Is the PINK wire connected to GROUND? (Legally in most states it should be connected to something that is only at GROUND when the vehicle is in PARK). When this wire is not at GROUND potential the video screen does not come on and stays black in any of the VIDEO modes.
  • When the source is RADIO the screen will function no matter what pink has going on.

  • The PINK wire is a NEGATIVE ENABLE but I don't know if it knows it.
  • When source is DVD with a DVD loaded you should hear the audio even thought the screen is black, of course if its sitting on a DVD menu with no sound you won't really know.
  • This is a PINK wire coming from the head units modular plug. not the bundle of wires that comes through the grommet but the plug that is removable. Not to imply that I have ever seen another pink wire. Well once I drank a lot of tequila ... not a pink wire. never mind.
  • While the wire was labeled on the OEM harness I have seen, the OEM wiring diagrams I have seen only have the description "PARKING" but no color code.
  • Feel free to repost or contact if the pink wire is grounded and the video screen is still acting the fool.

I just bought an XO1915BT DVD player and installed it. I have the pink brake wire grounded with the other ground. It worked fine for me until I tried putting a DVD in. It played the FBI warning on the DVD...

this is your owners manual for your radio
it shows me the pink wire is not for parking break but remote control for amp

gray wire is your parking break wire

i think you fried you dvd/radio

Ddx512 Kenwood Parking off problem

Indash DVD units are programmed not to allow DVD's to play while the car is in motion. The unit only allows DVD viewing when the car is parked and the parking brake activated.

To get around this, you simply splice the parking break wire from the radio to the -NEG wire of the radio.

If this doesnt help let me know.

Mute keeps activating by itself

easy guys ill explain, if you pull the deck out and expose the wiring in the back you will see a small pink wire with a plastic and metal end, that wire is your parking break bypass wire,wut i did with my car was created a switch, its very easy, all you need to do is go to radio and purchase a ON/Off switch, it will have only two metal connector ends on that switch, basically all ya gotta do is find a suitable grounding spot for the negative or OFF side of the switch and then for the positive guessed it attach the pink wire to the positive side. I had to make the pink wire longer for my switch location so if you know how to solder I wuld reccomend doing that than any other ghetto method, such as electric taping it and calling it a day, ding that may damage the system in the future

Xo vision xod-1730 product showing no image?

to watch dvd video on xod1730 like what adamdog said you need to attach/mix the pink/braking wire to black/ground wire and if you want to disable the pink/braking wire all you have to do is not to attach it to black wire or any wire and cover pink end wire with electric tape.

Parking brake hook up

This wire goes to the "Hot" side of the parking break switch... When the Parking Break is put on, a switch is closed, thus putting an "Earth" on this wire.. Ya can often bypass this by connecting to earth. Sometimes this wire can be "Hot" +12v so B4 doing anything with unit "On" check this wire for any Voltage.
