We are proud new to us 2012 journey owners. Our previous vehicle had a back up camera, the journey does not. I would like to add a new rear view mirror/ back up camera combo. Does anyone done this or have any tips or suggestions. I have found some el cheapo models on amazon and some high end models that look like o.e.. I am really liking the rydeen models. I am leaning towards the wired versions over the wireless models due to interference issues.
