Brake bypass for Sony cdx-m9900

Where can I connect the blue/white stripe wire besides the parking brake so I can get video all the time?

    I have a sony dvx 2000 and it will not play the dvd even when grounded? Do I need a toggle switch? Do you have the switch in the off (ungrounded) position and then throw the switch on to show the unit a ground? It is a green wire. There is no safety issue in my case-I have installed it in my camper!

    Please advise?

Ok I have to say this before helping you. This is a safety feature, when you are driving you should be driving not watching a video, now since this is a technical forum and not a saftey forum here is your answer. First get a toggle switch conncet one end to ground and the other to the wire so that on means grounded and off is ungrounded. this way when you are driviing it will look like the parking break is on. Now some systems are smart and look for a series of things to indicate that the safety protocols may have been defeated, so what you need to do is test this out when the car is moving throw the toggle switch into the grounded position and your video should play. when you stop the car and exit put the switch into the off position. This should work for you. Again don't do this because you should have your full attention on the road.

    Hello Houseman

    I gather that you did not like my safety message, even though I did show you how to defeat a safety measure. But that's ok, it serves me right. I thank you for opening my eyes to the fact that some folks are going to do dumb stuff no matter how it affects others, and for my part in that I feel ashamed, so I will no longer be answering these kind of requests because we all have choices in life and I prefer to make the right ones. Take care

I have a pioneer avh-p2300dvd in my car and i hooked up the parking break input to +12 volts because i want to be able to watch dvd's while driving(for my son in passenger seat) now my screen is stuck...


The parking brake (light green) connection needs to be connected to a (-) ground (black) wire, not a +12V wire. While it won't damage the unit to put +12V power to that wire, it does need to see a (-) chassis ground to view video while in motion. If changing this wire to ground still doesn't offer the solution, your Pioneer may require wiring of a relay as is necessary on several newer Pioneer navigation units.
Some Pioneer radios will still not allow video to be viewed even if the parking brake wire is grounded. For these units, I recommend using a standard 12V automotive relay (Bosch type). I would recommend consulting a professional installer if you are unsure about wiring this relay. Otherwise, if you are comfortable/knowledgeable, the instructions for wiring the relay are as follows:
85 - chassis ground86 - Blue/white stripe (remote turn-on lead from Pioneer)87 - chassis ground30 - Light green (parking brake lead of Pioneer)
The wiring of the relay will cause the parking brake lead to see the ground wire at the same time that the Pioneer actually powers up. This delay can be necessary for viewing video. An optional timing device can be wired in to do the same function such as PAC electronics' PTR-7.
The message that you are receiving for "screen image may appear reversed" is typically only visible when a reverse camera is used. For this, the Pioneer has a separate purple/white stripe wire for +12V reverse input.
I hope that this information was helpful.- Elliot

How to play dvd video when driving my car


Most wiring harnesses have a solid orage wire for illumination of the radio2_bing.gif and also have an orange wire with a white stripe for dimming purposes. Most radios do not use this dimming feature. Connect the brake wire to this wire and your able to watch your movies whenever you want. All the wire is looking for is a signal. It cannot differentiate between a parking brake signal and a non-parking brake signal. Just remember to be safe and pay attention to the road. Oh, and most states have laws governing the use of video playing in plain sight of the driver. BE CAREFUL!

BYPASS


The security device was created to avoid you from watching DVD's while driving. It is simple to bypass. Simply take the parking brake wire (blue/yellow stripe wire) and connect it to the a ground wire (all black wire). This will trick the DVD player into thinking that the car is in park with the parking brake on at all times.
