Audio Unit (Built in the audio-navigation unit)
WARNING: This page is about a different car, the 2013 Honda Fit and 2012 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.
The audio unit receives the audio driving instructions from the audio-navigation unit, and transmits the instructions through the front speakers even when the audio system is in use.
NOTE:
If the navigation volume and/or voice feed back is turned OFF, this feature is disabled.
