That’s awesome I’ve used flir on boats but never on a truck. So I used to be able to force the front cam but now I can only force the backup cam with rear defroster. Front defroster doesn’t do anything so maybe there is just a wiring issue with my front cam?it over rides the system to allow nav input while driving, force the front and rear cam at anytime and allows dvd/video in motion. if you press the front defrost twice the nav will stop tracking and then you can go into camera settings and turn on the front cam. i use it for video while driving because i have a flir camera on the truck so at night, i can reference the screen to objects much farther than what my lights can see, and since it has animal detection, i can make sure there are now effin cows in my way
