Sound Signal Circuit Between Stereo Component Tuner Assembly and Television Display Assembly

NAVIGATION: NAVIGATION SYSTEM: Sound Signal Circuit between Stereo Component Tuner Assembly and Television Display Assembly
- Sound Signal Circuit between Stereo Component Tuner Assembly and Television Display Assembly

DESCRIPTION

The television display assembly sends an RSE sound signal to the navigation receiver assembly via this circuit and the stereo component tuner assembly, multi-media interface ECU.

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 tuner assembly, multi-media interface ECU, stereo component amplifier, navigation receiver assembly or speakers.
