Help ! ! ! ! Installed Audiophile sub and now backup camera doesn't work
 

I added a audiophile sub to my 08 that has factory navigation. All the hookups along with the wires were exactly where people on here said they would be. Actually didn't have to do anything other than plug it in and everything worked. . . sub turned on and plays fine. Only problem is now the factory backup camera does't work:help::help:
