Speed Compensated Volume Feature

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

The ACM compensates for wind and road noise by adjusting the audio system volume based on the vehicle speed provided by the PCM over the CAN and the speed compensated volume setting.
