So I just bought a 2011 California special and since the GT/CS has a different spoiler so needless to say my car doesn't have a bank up Cam...I do have the OEM nav system with the car, does anyone know if it is possible to add an aftermarket camera onto the OEM radio without getting a new one since we want to keep it as stock as possible?

 

I got a gt 500 spoiler of American muscle and wanted my camera. I made this panel what you all think
