Review on Enhance Your Ride: PAC BCI-CH21 Backup Camera/Navigation Unlock Interface for Chrysler/Dodge/Jeep/RAM Vehicles by John Floyd

I bought this for my 2015 Jeep Wrangler JKU. This is by far the easiest option for adding a backup camera, disabling nav lock on the go, and adding another video source to your Jeep. No dealer flash required. I was offered $800 to install by two different installers. I've never done anything like this, but YouTube has tons of videos on how to remove the dash and radio (very easy), and some Jeep forums show how to install a backup camera (easy but time consuming to wire). The total assembly time was about 5 hours. The downside is that the PAC instructions are less informative. I had to call PAC twice to sort things out. Nothing fancy, but the instructions are for every Chrysler/Jeep/Fiat ever made and it's a bit of a hassle to figure out what they're talking about. In general, this is the cheapest and best way.
