    I'm sorry I don't understand the last part of your reply.

    The reverse switch switches +12V to the reverse lamp and the BLUE wire to the unit. (It does not ground.)

    In the case of the brake wire it seems the video is already getting 12V and is waiting to be grounded which means the driver applying the parking brake to make the ground connect and the video to work properly.

    Am I to assume it's the reverse with the reverse wire?? The camera is grounded out ready for 12V to be applied to it which it does when the driver puts the car in reverse????

    Just taking a blind shot here.

    I guess they do each differently cause the video is getting it's 12V from the nav unit whearas the reverse camera is getting it's 12V from the power going to the reverse lights in the rear of the car??????

    The reverse wire only tells the video display to switch sources, it has nothing to do with powering the backup camera. Connect it to power going to one of your reverse lights.

    Providing ACC power will keep the camera on all the time -- but you need to switch sources manually to see it.

    Ahhh, now I get it. Touchscreen changes sources between DVD, gps, etc..... this blue wire is not so much a power thing but a change source going to the screen so I can view the camera. Instead of me, putting it in reverse, touching the screen to view camera output, this blue wire does that for me. Very interesting and very, very helpful.

    I don't need a camera to help me drive in reverse. I bought the camera so, when I wanted to while I was driving, I could check out what's going on behind me.

    It has a 170 degree viewing angle. I plan to mount in somewhere on my back deck and I should be able to view BOTH blind spots and the driver directly behind me. For all this, doesn't seem like I even need to install this blue wire.

    You are correct -- you don't *need* to install the blue/reverse wire... But there's really no harm to it either.

    Thanks so much, everyone in all of my threads. Practice run before I soldered all the wires together was nothing short of perfect. I'll have it all installed and running strong by noon EST.

    Since the camera doesn't arrive for another 2 days, I'll have to pull it out to install it but no biggie. This forum made the experience much more pleasant and gave me much confidence. Thanks a lot.
