Introduction
It's probably the first time I've been happy to see it rain! I was on my way home after the retrofit and it started raining, my wipers automatically started. The light switch was on AUTO and all lights suddenly turned on, it was now dark outside. The retrofit also included automatic dimming of the rear center mirror.Time
Windshield installation: 3 hoursOther installation: 2-3 hours
Installation & Guide
The installation of the windshield was done at an authorized shop. All other installation was done by the user Discoboy from Vagcars.dk (Denmark)Unfortunately I cannot help you with a guide, this is not an easy installation so I would recommend you use an authorized shop. You can however purchase a cablekit and now that I watched another person do the retrofit it do not look like an impossible job.
Usage
Automatic Rear Center Mirror DimmingOn the front of the mirror a on/off button is located. If the button is on, it is lid with green light, and will automatically dimm if dazzled.
Automatic Light Function
On the light switch, you will find a new setting named "AUTO". When this is selected, the rain/light sensor will automatically communicate to the car if it is dark outside or not, and control the interior lights. It can also control your daylights, but mine are still standard.
Rain Sensor
The stalk where you configure the wipers needs to be in position 1. Position 0 is default and where the wipers are OFF, Pull it up to enable. Position 1 is where you usually could configure the speed of the wipers, now you configure how sensitive the rain sensor should be.
