On activation of the Mute line, the audio will switchover to the handsfree kit.

You can also use this harness to integrate audio into your car stereo from other mono sources by triggering the mute enable line (navigation units, radar detectors, CB radios, etc.).  A carkit-specific adapter harness may be required for your installation (I have some of these in my booth), or the connections can be made individually.  Available on the connection to the carkit is:

VBATT - constant +12V power supply

Ground - chassis ground

Ignition - switched +12V signal

Mute - active-low trigger Mute connection

Speaker (+) - differential mono audio signal from the carkit or device

Speaker (-) - differential mono audio signal from the carkit or device
