Communication Signal

AV control unit is connected to TCU via USB communication, and it receives the Telematics information received by TCU and gives the display and sound output. Telematics operation signals and sound signals are also sent to TCU.

Auto light adjustment function

Auto light adjustment function automatically dims/brightens the display according to the ambient light when the lighting switch is in the 1st or 2nd position. Whether or not the display is dimmed when the lighting switch is in the 1st position or 2nd position is determined by the output condition of the dimming signal output from the BCM to the AV control unit. Even if the lighting switch is in the 1st position or 2nd position, the display may not be dimmed depending on the ambient light sensed by the auto light sensor.
