hey everyone
just bought a DUAL xdvd8180 in dash monitor, and it won't play dvd's unless the parking brake is up, i knew this before i bought it, becasue i know theres a way around it, i just don't know how to do it....all help is appreciated

thank you

and before anybody says anything stupid like "you shouldn't be wathin tv" i drive to milwaukee everyother weekend and bring either my lil brother or my neice to and from moms or sisters house-dinner every other sunday there-and if anyone has kids....well i think you get the point

thank you

The park brake has a ground switch that grounds the trunk poper relay so you can't open the trunk while driving.

Sounds like it got tied into that curcuit. Might just need to rewire to a different point.
This is for Auto or manual so look at the e-brake line.

Most manufactures offer their own parking brake bypass module, so you might be able to get one right from them (or find one on Ebay).

Who installed it? Unless it has little laser beams scanning to check the position of the handle, (which wouldn't work anyway because the Fiero handle goes back down) it has to be getting an input from the brake light. Just put constant 12V on that wire and DVD all the time.

nobody it's not installed yet...and i want to enable the dvd player while the car is in motion

Some work on a 12 volt signal and some work on a ground and some use the input from the VSS to disable the main screen from movie viewing. If you know which one you need all you need is to supply whichever signal the wire is expecting. The Kenwood CD/DVD/Navigation system in my wife's car has this wire grounded and will play movies while driving on the main screen. You can set up a remote screen if your unit offers this feature. The remote screens will usually play regardless of if the car has the parking brake on or not, as they are supposed to be in the rear of the car and aren't supposed to be able to distract you. Once I set up the remote screens in my wife's car I will connect the disable wire correctly so I won't be able to see movies unless the car is parked.
Try scanning the wiring diagram for this unit and post it here. I bet someone will be able to help you better with this information.

Oh then you are just reading from the marketing hype. I wouldn't worry about it. I've installed DVD in three cars and never once saw anything that prevented it from working under any conditions.

If there's a brake input wire, , ignore it, ground it, or put 12V on it, one of those will work for sure.

put like a 12v battery on it and it will work??

I did a search on Google, and found this on another forum.


"These methods have worked on a variety of Dual DVD systems (mainly XDVD8181, also XDVD710), unsuprisingly, since Dual stated to me that most installations have the same codes.

WARNING! It is usually ILLEGAL and most of all UNSAFE to drive while watching video. I only watch video while parked, and I suggest you do the same. This is for demonstration purposes only, if you use these codes, you do so at your own risk.

STEP ONE. Ground the E-Brake wire.
No matter which method you use, you must ground the brake detection wire. I suggest you tap it into the ground wire on your wiring harness (ensures a good ground).

1. FACTORY RESET METHOD (Temporary)
(This isn't the most effective, but it is the easiest to try, so it's worth a shot since it apparently works on some units.)
** Go to the Menu
** Get to the Settings Menu
** Select <yes> to Reset to Factory Settings.

Have recently heard complaints of this method not being permanent, as this is needed everytime they want to watch a DVD. Also, radio and screen angle presets are lost.

----------------

2. AUDIO CD METHOD (Permanent)
** Insert Audio CD
** Press PLAY
** Press STOP twice on remote
** Enter 26604 on remote
** Press ENTER
** Take out Audio CD and Insert a DVD

3. DVD METHOD (Permanent)
** Insert a DVD
** Let it play until you hear sound
** Press STOP twice on remote
** Enter 26604
** Press ENTER

The blue warning screen should immediately go away after pressing the last digit of "26604." Still press ENTER as a precaution."

It sounds more complicated than it needs to be. I don't know why you need all that firmware hacking, it's just a stupid wire.

I did a search on Google, and every site I came to, had the same fixes; so they must need a proper "code" to bypass the parking brake input.

You are probably right, but I've never even seen a parking brake wire on the half dozen auto DVD platyers that I've bought. The one in my car has power, ground, audio and video out, that's it.

And every one I've used seems to be running the exact same firmware, (probably written 10 years ago and copied by every manufacturer).

Oh well, if it works then go for it.

Every unit I have seen has a simple brake wire input ,not a special digital one or any other type that needs codes. adding a DPDT switch that either connects the Brake wire or grounds it will work perfectly, it allows you to flip a switch and say "see officer, it will not play when I am driving" and then flip it back after the cop leaves. works far better than any of the codes out there. The codes are typically for people that get frightened of wires and changing them, or they went and had a "professional" install it and are afraid of changing that.

The correct way is, Ground the wire. you will see warnings all over in the manual about how you are letting the terrorists destroy freedom and killing kittens by doing it, but go ahead. Be warned though, if you are in an accident and the police or insurance company finds out your system is wired to play while driving they will instantly assume you were and make you at fault or worse. I suggest a stealthy switch like I mentioned to cover all your bases.

Note: I am used to the Pioneer, Kenwood and JVC units.

Ok, heres your problem, I have the same dvd player in my dodge. you can not just hook it up to a 12v power or ground (I thought that too) because it makes you engage, disengage and then engage that parking brake to make sure you dont do that. What i did was hook it up the wire right on the ebrake that turns your light on and becuse its a dodge and the ebrake is so long to engage I can engage the brake, release and then push it just enough to make the light come on but not enough to engage the brake and then run it like that, but im sure you could accomplish the same thing by hooking it up to a switch with 12v ground or power I dont rember with it needed and then you can toggle it on and off

I can't believe it hasn't been asked yet. What's the model # of the unit I'll pull the wiring info and give you a list of not only how to hook it up but also how to install a bypass switch. Ask yellowstone about my wiring info it's good info, Haven't let him down with it.

it is a dual xdvd8180 that is the model number-first sentence i put it there-

thank you for the help

and no i don't have an alarm

LOL that's a pain in the arse now... The newer Pioneer Z1 needs to have an extra wire added to the harness and grounded (as well as grounding the park brake wire), the older one needed to have the lights flashed on and off several times. I hear the future ones are going to monitor your speed via GPS so there will be no obvious work-around. Different manufactureres have different ways of trying to stay legal. Even with the bypass, I still get the annoying "press OK if you agree you're not going to drive and kill someone while watching TV" screen every time I turn on the DVD or Nav. I didn't do it for DVD's though, but so I could enter addresses while driving. Yeah, not a whole lot safer than watching DVD's... I know.

how do i 'ground" a wire into the wiring harness? can anybody give me very a very detailed explaination-or possibly a diagram

thank you so much for the help

From what a buddy of mine just told me, the lower end brands like Dual, Jensen and Alpine need a "pulse box" or a code entered all the time. I guess search for "car dvd pulse box" on google to find one. It will do what you want it to do. A toggle switch would also do it easily, just flip the switch on off on to do whatever dance it wants to see to believe the brake is on.

XDVD8180 OPERATION
DVD Operation - Parking Brake Initialization
• The video display of the in-dash unit will not operate while the vehicle is
moving. This is a safety feature to prevent driver distraction. In-dash video
functions will only operate when vehicle is in Park and the PARKING BRAKE

Follow these two initialization procedures carefully to allow video playback on
There are two situations that start the PARKING BRAKE sequence.
First situation is while driving:
1) Stop vehicle, put in Park, make sure PARKING BRAKE is off/released.
2) Depress PARKING BRAKE for 1 second.
3) Release PARKING BRAKE for 1 second.
4) Depress PARKING BRAKE permanently.
Note:
Once above procedure 1-4 is completed, video will display in about 6 seconds.
Second situation is while already parked and the PARKING BRAKE is already
applied:
1) Keep vehicle in Park, PARKING BRAKE should be on.
2) Release PARKING BRAKE for 1 second.
3) Depress PARKING BRAKE for 1 second.
4) Release PARKING BRAKE for 1 second.
5) Depress PARKING BRAKE permanently.
Notes:
Once 2nd procedure 1-5 is completed, video will display in approx. 6 seconds.
The transition time must be less than 2 seconds between depress and release.
This procedure will have to repeated when the IGN is turned off.
Take yellow wire and hook two wires to it. Attach one to a toggle switch that you hide. Other side of the switch attach to a ground source. The other wire needs a Diode installed inline with it to keep your Brake light off when using the bypass switch. a 1n4001 diode will work just fine. Install the diode in wire with the White stripe towards the e-brake connection. If you get it backward the light will come on and the ebrake handle connection will not operate the dvd player.

Now you may ask why make 2 connections when the switch is the most desired? SIMPLE! Cops check around here and will make you turn it on. Some are keen on the switches, so they will make you operate the brake to turn on the screen as a check. And if you get in an accident you will be checked as well.
