Amplified Systems
For vehicles with factory amplified sound systems: The factory system accepts two channel audio only. The factory amplifier fading is controlled by data communication from the factory radio. Therefore, the aftermarket radio will not have the capability to control the factory amplifier. Please connect the front outputs of the aftermarket radio to the rear inputs of the 22-pin Scosche connector. This will allow Bluetooth hands-free audio and navigation voice prompts to be heard. The rear speaker outputs of the aftermarket radio will not be used. The factory amplifier BALANCE and FADER is set to center by the interface.
