Do you want it to be semi-OEM, i.e., display on the PCM screen when car is reversed? If so, I would call NAV-TV and ask them about solutions for your car, and who might be a good local installer, if you don't want to DIY.
https://navtv.com/ Something like this would work, probably:
https://navtv.com/products/?q=KIT265+The kit alone is $800, total cost installed seems to run in the $1,000-1200 range, from what I've seen.
If you just want to see behind you, and don't care about an OEM setup, there are cheaper wireless "stand-alone" solutions.
