You can install a in motion video bypass switch so your co-pilot can watch a movie, or video dvd while you are moving. The new generation NEX double din receivers with 7" screen are programed to only work when you are parked, with the emergency brake on. Then Lexus, adds a new hurdle in their OEM screen,a speed sensor, which will turn the video off when the vehicle is moving 3 mph or faster. An override is necessary. Born2x did a really cool override switch with contemporary lighted momentary switches, cool ! or if you want to be extremely discreet and hide it in plain sight, I did a micro switch up against the cigarette lighter. Hard to see , but that's the object. So contemporary bling or discreet placement, it's all good !
