So I have a 22.5 ltz, it's the "refreshed model", I want to add a bed view cam. Is that already provided in the module it currently has? Also would I need to do any programming for the head unit to kno/give me a digital button to use the bed view within the radio itself?

Hello all , first time posting here. So I have a question I want to add a bed cam/rear view mirror cam to my 22 Silverado with the new infotainment system. I wanted to see if anyone out there has done this or if it is even possible before I buy all the parts. Plz any insight/info is helpful.
