date application information.
Active noise cancellation is an OE module that helps reduce unwanted background noise. Microphones mounted throughout the
vehicles are used to monitor sound levels and frequencies inside the vehicle’s cabin. The factory ANC generates an inverted signal from
the factory speakers to cancel out unwanted cabin noise.
It is recommended that the RPO code is double check to confirm application. The RPO Codes can be found on a placard labeled “Service
Parts Identification” in the glove box, on the trunk floor or inside the driver's door panel.
