Sound Signal Circuit Between Navigation Receiver Assembly and Stereo Component Tuner Assembly

NAVIGATION / MULTI INFO DISPLAY: NAVIGATION SYSTEM: Sound Signal Circuit between Navigation Receiver Assembly and Stereo Component Tuner Assembly
- Sound Signal Circuit between Navigation Receiver Assembly and Stereo Component Tuner Assembly

DESCRIPTION

The stereo component tuner assembly sends satellite radio sound signals to the navigation receiver assembly via the sound signal circuit.

The sound signal that has been sent is amplified by the stereo component amplifier assembly, and then is sent to the speakers.

If there is an open or short in the circuit, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly, navigation receiver assembly or speakers.
