Brake bypass for Sony cdx-m9900

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

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.

cheers lad solved my problem, and im not the sort of dick head to use it while im driving like the other knob, it was just easier than ripping my console out to get to the handbreak wiring
