I had both the rain sensor and dimming mirror retrofit done at the same time. From reading the manual it describes being able to change the sensitivity of the rain sensor by turning the **** with the picture of the wiper on it to one of 6 settings. The manual says that you will have the change acknowledged by one wipe of the wipers. Since I had the retrofit done, it takes a whole lot of rain to get my wipers to wipe making this feature virtually worthless. I tried increasing the sensitivity by turning the **** and got no change and no confirmatory wipe. I had my car into the dealer today for the seat recall and asked if the rain sensor retrofit was set up / installed correctly. The tech came back and stated the sensitivity function only works on the factory installed and not on the retrofit because it has a different controller.

From anyone else that has the rain sensor retrofit is this true?
