Audio Guidance
WARNING: This page is about a different car, the 2008 Acura TL and 2007 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.
The navigation unit transmits audio driving instructions before entering an intersection or passing a junction. The audio instructions come through the audio unit to the front speakers.
NOTE:
The front speakers are muted whenever the navigation system is giving guidance commands, and all of the speakers when the voice control system is being used.
