Jvc kd-avx11 have power and sound but no picture, what colour is the park brake wire?

Check to ensure the wire to your parking brake is grounded. You can also set a dead ground on the cable and the head unit will think you have the parking brake enabled at all times.

No, the cars computer doesn't have any effect on an after market head unit.Just a bad radio..

According to Crutchfield.com, which does hands-on research, "The KS-PD100 is not compatible with the iPod touch (1st, 2nd generation) or iPhone/iPhone 3G. This iPod interface will also not charge the iPod nano (4th generation)."
I'm currently a victim to this JVC abandonment too.
I'm looking for a 3rd party adapter that may solve this... Jvc better get on the ball because Ipods are moving forward with newer models...
I'll get back to you if I find a compatible adapter..

your car probably wont have one this wire is designed to be hooked to the park brake switch wire so you cannot watch movies going down road.as this is illegal. the wire gorunds when park brake is pressed. splice it into the wire on brake

check to be sure the deck has 12v+ switched to the red wire, 12v+ constant to the yellow wire, and that the black is grounded well.. If all of that is correct, you are probably looking at a unit in need of repair.

try and connect the green long wire to a earth. when i had mine installed they just connected it straight to the back of the unit earth point at the back in the middle

Ground the handbrake wire to the outerpart of the "line out" connector if it's not in use, works a treat

ground parking wire with black ground

ground the e-brake wire to something other than the e-brake start the dvd when you hear sound press "stop stop" then enter the code 26604 then press "enter" you will have to do this every time you want to watch a movie but it works.

You'll have to connect the wire "parking brake" at the back of the JVC to your ground wire (black)!
