When the car moves and the emergancy brake is off the DVD is blacked out. Well if the Navigation system didn't know the car was moving the the DVD would continue to play. Correct? To my knowledge there are at least three maybe four ways the Navigation knows the car is moving One, the emergancy brake is not on. Two, the GPS antenna picks up signal and tells Nav. sys. it's moving. Three, The GYRO senses movement. Four the VSS wire sends movement signal.
Seems to me that if someone pulled the emergancy brake up one click [or grounded it going to the Nav. sys.] and covered the GPS Antenna with a piece of alum. foil to block the Sat, signal and disconnected the VSS wire with a toggle switch. The Nav. system might not know the car is moving and the DVD might play while driving so the passanger can see it. Then just remove the foil and throw switch and you are back to Navigating. Has anyone tried these three steps at the same time. I do not know enough to know there the VSS wire or the GPS Antenna is located to cover it or to temporally disconnect it with a switch. If this makes sense I wish some would try it and let us know if it works. If the GRYO also plays a part in this I guess that complicates thangs quite a bit. I wouldn't know how to temporally disable it. Maybe someome out there knows how. I wish the 2007 GX470 could be disabled like the earlier models
