    AVH - P4900! I have a GMCO Chime Module in my car with the new AVH-P4900 Deck! I can't view any video because it is saying that video is not available while driving! Can someone tell me how I can get the video to work without messing with my e-brake!? I have no experience and would love to get this thing fixed so I can watch the video!

    I hooked up all the wires like they are suppoised to be, but im not getting any sound. The deck shows the cd being played, again no sound, can this have something to do with the brake switch?

I have bypassed many units with an ebrake safety.. best bet would be a toggle switch, connect to ground. i don't believe your unit uses a 12v+ for the ebrake signal, but if it does, connecting the wire to ground first won't harm the unit, try it out, flip the switch on-off-on and take it for a test drive. if it works, you are good to go, if not, test it with the positive.

if you need any further help, feel free to post a followup,
trin

There is no video on my kenwood ddx8017, why? Do i have to bypass the parking break wire? which one is it, the solid green, or red with black, or pink?


If you want to watch videos on your unit it is necessary to bypass the parking brake wire from the Kenwood unit. The parking brake wire is light green and the best possible way to bypass the unit is by installing a toggle switch. The toggle switch should be a two wire device. Connect one wire to ground and the other wire to the parking brake wire from the unit. This will allow you to switch the supply on the wire to ground when needed.
Also, in some older Kenwood units you could just as easily connect the parking brake wire to ground and be done with it but, it does not always work.

Bypass ebrake with relay on a pioneer avh-p5700


Go to any auto parts store and purchase a four wire relay and wire it up as follows: The relay will have numbers written on the bottom for each pin. The wire from the parking brake from the H/U to 87. Ground to 85 and 30. Remote from the H/U to 86. This will give you an automatic bypass to the DVD lockout. If you want to just put a switch to do this manually you can also. Go to Radio Shack and buy a momentary push button switch, part number 275-1548. Take the green wire coming out of the unit. Strip the wire, and attach it to one of of the pins on the relay switch. It doesn't matter which one. Buy a standard 16 gauge wire from Radio Shack and connect it to the other pin on the switch, then connect the other end of it to a grounded connection on your vehicle. Now, when you play a DVD, the warning screen will come on. Just press the button on the switch and it will go away, since it tricks the receiver into thinking you have engaged the parking brake. Like someone said before, it is illegal in just about all states to have a dvd or other video playing if the driver can see it and the car is moving. This method is used because the lockout not only keeps you from seeing videos but also locks out some features which many feel have nothing to do with safety and they need it.

Creative Inspire 5300 Volume Control broken!


For those searching the answer "How to replace/repair Creative Inspire 5300 volume control":

Its simple : looking at the back of the suboofer, the pins are as follows from top right, clockwise : LED VDD , Balance pot middle leg, GND, pots + legs, Volume pot middle leg, on switch input. Connect one pots ends to GND and the other ends to pots +, connect a switch on GND and on switch input, anode of led to LED VDD, cathode to GND (there is a 1,8k resistor inside so no external resistor needed)

Bypass e-brake wire


Hi,

Normally, to by-pass, you need to ground the yellow/blue wire of the Dual XDVD 8183. This would simulate the condition where the vehicle is in “Park” and the parking brake is engaged thus allowing the unit to operate even if the vehicle in reality is not in “Park” and/or the parking brake is not engaged. Some regions have restrictions on this condition.

Additionally, some versions would require a SPDT switch moving the yellow/blue wire from 12V+ to GND to be bypassed.

Hope this be of help/idea. Pls post back how things turned out or should you need additional information. A friendly reminder pls, "Drive Safe".

Good luck and Kind regards.

Hi,

Normally, the emergency/parking brake has to be activated/engaged for the video player to operate.

By bypassing, you are simulating this condition even if in reality, the emergency/parking brake is not activated/engaged.

Solution > ground the video player's brake sensor wire rather than connect it to its intended connection point.

In some brands/model/versions of the video player, this would be light green (Pioneer, Clarion, JVC), green (Kenwood),

In some other rands/model/versions of the video player, there would be a bypass switch underneath a sticker, others would need a special adapter, still others have bypass option/feature in the menu/setup and some would require a toggle switch that would connect the dvd brake wire from positive to ground.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information. A reminder pls, in some regions bypassing is not allowed.

Good luck and kind regards.
