Seems strange that my radio does not dim its brightness at night. My last radio was a POS clarion and even it dimmed itself when my auto headlights turned on. Is this a wiring issue? I have read the entire length of the manual and can find no reference to this.

Illumination wire isn't connected.

What does it connect to? I apoligize, I have a ton of wires behind my dash. Its because I have a GM Onstar unit pluged in back there. It made it difficut to tell what wires go where. I have the same issue with the backup camera. The brake light is wired to the violet wire on the receiver. Another member says that I have to get power for the camera from somewhere else however the camera doesnt have another wire. The camera works because it is getting power from the lights. It has 1 harness that both connects the camera to the backup lights and one wire that splits off and goes to the reverse wire and yet another wire that that splits off that for video

Any circuit that gets power when your lights are on.

look at the manual for the illumination wire, it is probably orange. use that.... also make sure the camera is turned on in the settings on your headunit and make sure the reverse wire is hooked up from the headunit to an output that changes when you car is in reverse, if you cannot find this wire than go directly to the postive wire on your reverse light at the back of your car.

Is there anyway do disable the dimmer on the AVH8400 ?

I think you can turn it off on the unit. Or cut the orange wire!
