Its awfull that they have to dictate when you can watch a DVD, I bet you cannot listen to MP3's on DVD also. I installed my set and never followed the warnings, My radio is set on Switches that I can activate when I want to. My Cam is on a toggle SW. so I can see in the rear like a mirror, when I drive I can see the rear of my trailer on the deck if I switch to rear cam. Can you imagine me using a cam that the truck has to be on reverse. These laws are for fools and we pay money for these units that are installed to be unusable. Sometimes I wonder how people can exist on their own without the knowledge of fixing the designed flaws that exist in the product we buy everyday, and we pay a lot. If I can afford $3200 for a unit I surely am smart enough , not to watch a Movie while driving. I sure spend a lot of time rearraging my gadgets to satisfy my demands. PC's are the worst they are so demanding and then there is my truck Umm I surely don't have it Ford stock for sure. Every vehicle I ever had I have to build something on it to make it worth owning and be more dependable.
