Rear Audio Separation Module (RAS)
The rear audio separation module (RAS) (16/122) is designed to redirect audio signals from the car's internal audio system or from the system's DVD player to the rear speakers (16/5, 16/6, 16/57 and 16/58).
When the unit is in normal mode, audio signals are routed from the front audio system to the rear speakers.
The remote control can be used to activate the rear audio separation module (RAS). Audio signals from the front audio system will then be replaced with audio signals from the rear seat entertainment system.
Which audio channel is connected to the rear speakers is determined by which screen the remote control is aimed at when the button to activate the rear audio separation module (RAS) is pressed.
If a parking assistance system is installed, the control module is temporarily deactivated via an input when reverse gear is engaged. The deactivation signal comes from the same voltage circuit the drives the reversing lights. The parking assistance system signals will then be heard via the rear speakers.
