Fig. 85 Heat-reflective windshield with communications window (blue shaded area).
Windshields made of insulating glass have a transparent metallic infrared-reflecting coating. There is an uncoated area (communications window) just above the inside rearview mirror ⇒ Fig. 85 . This serves as a communications window for transmitting signals to and from electronic components and accessories.
The uncoated area must not be blocked on the inside or outside or covered with stickers because this can cause the electronic components to malfunction.
