Product Updates (Firmware)

1. Vehicles equipped with an overhead screen only:

    In this application the 

GMRVD2 

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 

GMRVD2

, A/V will be passed from the aftermarket head unit to the rear screen and audio 

    can be heard through the headphones. The 

GMRVD2

 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. 

The RP5-GM32 can be updated with new firmware as it becomes available using the PAC-UP interface updater (sold separately). 

Please visit www.pac-audio.com/firmware for available updates.
