I am certainly not an expert on the subject but I did manage to install the following and make it work on my 2010 Sahara.
RBZ radio, the latest model, sourced from e-bay,
Parkview camera and wiring harness intended for a Commander,
Homemade housing made from a trailer hitch brake light unit from Harbor Freight.
The RBZ radio is already set up to accept the camera signal and it works very well. Installation was not terribly difficult but figuring out what to hook where was trying.
The good part is it is all Mopar and works well together.
