I just purchased a 2012 Chrysler Limited. I have a backup camera in the upper tail light but I do not have the screen in the dashboard for navigation or the backup camera I think it goes up to the rear view mirror but I'm not getting nothing in the rearview mirror or on the dash. Can anybody tell me where the screen might be located either in the mirror or in that Dash console. I do not have the GPS navigation touch screen my display screen is about 4 by 5 if that. I can put the car in reverse but I cannot see through the backup camera
