Circuit / System Description
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
The infra red (IR) sensors for this system are on the lower edge of each display screen and on the forward facing portion of the earpiece of each set of headphones. For optimum IR transmission, remove any obstacles between the headphones and the display screens. IR transmission can be degraded during conditions of direct sunlight inside the vehicle.
