As long as you have a touch screen radio like the 430 you can add a BUC. You need the camera and harness to hook it to the radio( special plug )and then the dealer has to flash the vehicle to activate it if you go MOPAR/OEM hookup. You can also get a LockPick harness that eliminates the dealer flash and lets you use any aftermarket camera of choice with a RCA type jack.
The MOPAR BUC kit specifically for a Patriot uses the rearview mirror( replaces it ). You could modify a kit for another vehicle to work as well if you wanted it to run through the head unit.
