After the white paper cheat worked I couldn't even move after a week, I realized something else was wrong. So I ordered these and I have the 600 series and thought the updated is what I need and why 4 stars but it's not. Yes everything else came and came as it should except 1 bumper sensor. So it's together and working, I just had to take the old housing and guts off the new sensor and reassemble it to fit. Aside from that hiccup, it works great
