Accessories and extra equipment
Certain accessories only function when associated software is installed in the car's computer system. Volvo therefore recommends that you always contact an authorised Volvo workshop before installing accessories or extra equipment which are connected to or affect the electrical system.
The windscreen is equipped with a heat-reflecting film (IR) that reduces the solar heat radiation into the passenger compartment.
The positioning of electronic equipment, such as a transponder, behind a glass surface with heat-reflecting film may affect its function and performance.
For the optimal function of electronic equipment, it should be positioned on the part of the windscreen with no heat-reflecting film (see the highlighted area in the above illustration).
