Just installed a Kenwood DDX-7015 w/ the navigation system, and now I can't get the overhead DVD unit to work. I have it all powered up with both 12v's going to the unit but it turns on then turns off in about 5 seconds. I place the factory unit in and all is fine. I also checked the voltage and amps from the factory unit and tried to simulate the same power but no luck. The weird thing is that if you hold the power button down it turns on and the unit works but when you let go it shuts off. fficeffice" /><O></O>

If someone if familiar with this please by all means help me out.<O></O>

 

The factory unit has a wire that goes to all the remote equipment such as the DVd that tells them that the audio system is on. There is a post on the 20 pin wiring diagram here that shows that. The dvd requires 3 voltage sources. One battery- for memory, one for illumination and the other to turn it on. Search for dvd wiring.

 

I have all 3 wires hooked up, I even check the voltage coming from the HU and placed a resistor to achieve the same voltage. Still comes on and shuts off, put the stock HU and it works fine. Very lost please help

 

i am having the exact same issue with my 2005 mercury mountaineer.....someones gotta be able to figure this thing out already....

if someone knows....please post the answer in detail with some diagrams and some explanations so i can give it to my installers so they know.

 

I did a little more checking and came to the conclusion that the stock HU has 2 wires for data communications in the 16 pin behind the HU without them the DVD won't work. I relocated the stock HU under the second row middle seat ran power to it and ran the ASYSON wire(12V turn-on) and the 2 data communications wires to the DVD and everything works fine. If anyone needs any wiring pinouts and connector views please give me your email address and i'll forward them over to you.

 

how exactly did you fix this problem. can you tell me in more detail. and is having the original hu necessary
