I have done some searching and cant seem to find anything. I am trying to install an aftermarket reverse camera using the A/V in input on our 2013 C-Max. Does anyone know if there is a way to disable the "Park Use Only" lock out that I can run the reverse camera in reverse or am I just barking up the wrong tree and Microsoft/Ford have defeated me? This was supposed to be a birthday surprise for the wife and I'm kinda going nuts..... Any help would be great! Thank you!

Update. The swap over took about 5 minutes including checking to see if the used light came with bulbs (it did). The part looks brand new and was professionally packed. A big thank you to hammysauto on eBay. The wifey is very happy now.

First of all, thanks for the info from all of you. I got a used one with no damage from eBay. $75 and included free shipping. I will take a look at it when it arrives Friday but was told its in like-new condition. For now I'm using clear packing tape to hold the 3 lens parts together on the housing.

So my wife just called and said she hit something and broke the rear passenger side tail light lens. I got a replacement from eBay but I am not 100% sure how to replace it. I'm handy enough to dig around and remove it without guidance, but was hoping that someone here had experience and could lend a how-to or advice. Thanks in advance.
