I haven't disconnected the rear speakers but I can absolutely guarantee that to be the truth. I hear the audible beeps coming from the rear speakers every time I back out of my garage.
The digital signal that goes into the NAV-TV processor from the factory ECM encodes the signal to the rear speakers. That's how the processor decodes it.
