Automatic Rear View Mirror Anti-Dazzle
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.
The upper electronic module receives data from two photo sensors, one on the front and one on the reverse of the rear view mirror. If the upper electronic module determines that the anti-dazzle function is required, a signal is sent to the electro-chromatic mirror which diffuses to the level required.
The signal transfer occurs internally in the rear view mirror, and is carried out directly between the upper electronic module and the anti-dazzle function.
CAUTION:
The rear view mirror with automatic anti-dazzle can only be installed in the factory. Upgrading to, or removing an anti-dazzle rear view mirror cannot be carried out after market due to software limitations.
