Rear Seat Entertainment (RSE); If equipped
1. Vehicles equipped with an overhead screen only:
In this application the
GMRVD
must be used in order to feed A/V into the factory screen from an aftermarket head unit (head
unit must support A/V out). With the
GMRVD
, A/V will be passed from the aftermarket head unit to the rear screen and audio
can be heard through the headphones. The
GMRVD
will also pass the Auxiliary inputs on the rear of the center console to the
aftermarket head unit.
2. Vehicles equipped with an overhead screen AND headrest monitors:
In this application the headrest monitors will function independently from the overhead monitor. Neither video or audio
can be passed to or from the headrest monitors. The overhead monitor will function exactly as described in #1.
OnStar Volume Adjustment for Vehicles w/o SWC
1. If SWC buttons are not present you must use the
programming button on the interface to control the OnStar
audio level during an OnStar connection.
2. When OnStar is active pressing the programming button
will raise the audio level 4 times before returning to the
original level.
