On my AVIC 8000 NEX I connected a small 12v digital recorder that I have mounted in my glove box that with some splitter cables allows me to record the front camera on my Vette it records automatically anytime it's running, I also have it hooked up so I can playback the video I recorded on the head unit, so yes it's possible with the right setup. You can read about my setup starting at post 47 from this thread in the Corvette Forum which you can find here. https://www.corvetteforum.com/forums/audio-electronics/4249922-new-pac-interface-3.html
