I had a stock backup camera in my 2007 jeep and upgraded the head unit to a Pioneer DMH 220EX unit off Amazon that hooked up directly to the camera.

I like the unit and it's full touchscreen. Have it in my 05 FXT now as well, just need to get a generic backup camera added and installed on the hatch door myself.

You can find all sorts of cameras, all depends on what features you want with it. I know the newer units have the turn lines and the colored length bars for distance too, but honestly, I don't even use those features.

Best of luck to ya! ✌️
