Provides an ON/OFF/ON signal and holds it, so you can play video on your AVH-P8400BH.
I was worried the deck would keep looking for an ON/OFF/ON every time you switch to video, but that doesn't seem to be the case. It sticks on.
You still have to touch OK to the warning about driving with video, once, each time the deck is turned on, though that's a part of the unit, not a fault of this switch.
You could always wire in a manual switch to achieve the same affect, and switch it on and off and on, but this is as easy to install and then you never have to worry about it again.
