Muting Signal Logic

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.

The audio muting logic is orchestrated by the audio-navigation unit. The audio-navigation unit determines what audio source has priority to use the speakers.

The priority of the audio sources is as follows:

HandsFreeLink has the highest priority, followed by, navigation, and finally the radio/CD player. The priority signal is passed by HandsFreeLink to the audio-navigation unit by dedicated mute wires. The navigation mute signal is passed to the stereo amplifier.

The audio-navigation unit temporarily disables the voice control buttons, but allows guidance to be heard.

When the navigation system sends out a voice route guidance command, the rear speakers are muted, and the navigation voice is heard in the front speakers.

When the navigation voice control system and HandsFreeLink is in use, the rear speakers are muted, and the navigation voice prompts are heard from the front speakers.
