Navigation Voice Circuit [08/2017 - 08/2019]: Description

This circuit is used when the voice guidance in the navigation system is on or an incoming cellular phone voice in the "Bluetooth" hands-free system is heard.

Using this circuit, the navigation receiver assembly sends the signals to the stereo component amplifier assembly.
