Circuit/System Description

The radio can command the seatback video display mode on vehicles equipped with rear seat entertainment (RSE) video. The radio utilizes discreet mode control circuits to each display to control the screen display mode via a pulse width modulated signal. If the display screen does not receive a signal, the display screen will operate in a default full screen mode.
