The audio sensors were installed as an option on our 2015. There is an audio on/off switch for the on the left side of the luggage compartment near the trunk light.My Grand Jeep Cherokee had all of that integrated into the NAV read-out. I miss it. The Mazda only has the lines and visual. No audio. For whatever reason, I miss the audio.
