Recently picked up a '21 Laramie, and the only option it didn't have that I wanted was the surround view camera. Is it possible to have this installed and software updated, or do I have to get an aftermarket kit? If the answer is aftermarket kit; is there any way to have it show up on the 12' screen already installed? I'd like to keep random extra screens to a minimum if at all possible. Thanks in advance for any info!
