Thank you for your solution, it works great,,,also thanks for pointing out saftey concerns, which i agree with, but I think you went to far suggesting I was one of those folks who do "dumb stuff"...thats what you should feel ashamed about BECAUSE this radio is being installed in the back of a limo,,but thanks for the tip it did work

Re: brake bypass for Sony cdx-m9900
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.

If its a dvd player one wire will be for brake "ground" (have to be in park in order to watch movie unless bypassed)
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

Most wiring harnesses have a solid orage wire for illumination of the radio 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!
If you want to by-pass the parking brake wire, here's how.

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.
