How do I bypass the parking break to alow my kids to watch movies while im driving? (Kenwood DNX7100)


The parking brake wire (light green) from the kenwood unit needs to see ground. You could either ground the wire or use a toggle switch to ground the wire.

XDVD700 Car DVD Player: I'M TRYING TO FIND BYPASS CODE?...


You do not need a bypass code. Pull out the stereo unit, take the parking brake wire and disconnect it from the parking brake sensor ground. Reconnect it to the radios ground wire and this will tell it that the vehicle is always in park and your videos will work while driving. It must be the stereos ground not just grounded to the frame or something. Must be a live source ground wire.

BYPASS EMERGENCY BRAKE WIRE


unhook your E-Brake wire and do the following:(2 options depending on DVD Unit)

If you have the old firmware then all you need to do is ground the parking brake wire
OR
if you have the new firmware(just bought the system) a toggle switch is involved:
1 - connect e-brake wire from dvd unit to the switch
2 - connect a ground wire from switch to the unit chassis(any good metal grounding surface will do)
3 - pop in a dvd, toggle the switch back and forth 2 or 3 times depending on what wire you placed where...and voilaa!! your dvd system should work in motion!!

DVD head units have one extra wire in their wiring harnesses, compared to a standard CD head unit. On my Jensen, it's a peach-colored wire, and is the activation wire for the DVD feature. During the installation, the instructions call for this wire to be tapped into the emergency brake indicator light wire. The reason is this:

The e-brake indicator light is what is called a "ground complete" circuit. That means that the bulb always has power applied, but when you pull the brake, that puts a ground to the wire and completes the circuit, allowing it to illuminate. The head unit sees this ground, and activates the DVD player.

In my Jensen unit, I simply ran this wire to a ground (I used a screw near the fuse box), and I put a switch on the wire, so I could break the ground contact at will. Jensen calls for a procedure to activate DVD playback. In their instructions, they tell you to select DVD from the option menu, and when the "lawyer screen" comes up (the one warning you to park before you watch a movie), you release the e-brake for 3-5 seconds, and then reapply it. To simulate that with the switch I used, I leave the switch closed (activated), and select DVD. Then I flip the switch "off" for 3-5 seconds, and flip it back "on". This tricks the head unit into thinking I put the e-brake off for a few seconds and then put it back on, and the movie will start. Then I can drive away.

Basically, ground the wire that is used for DVD activation, and put a switch inline on it. Then you can break and reapply the ground in whatever manner is required by the manufacturer of your head unit. If there is no off/on sequence with yours, as there is with mine, simply ground the wire to a screw inside the dashboard and you're done.
