Just curious on something. My new nav HU comes with the option of a back up camera. Does anyone know if there's a aftermarket piece that can be put in where the 4th brake light would go, at the bottom of the bumper, on my 2011? I know people add that xtra brake light but I was thinking it would be nice if you could throw a camera in there. Or maybe even a brake light/camera combo, if that's even possible.
