The Side View when turning with trailer hitched and connected properly , including the optional rear view camera installed per the very detailed instructions , plus a tow vehicle with the requisite towing package will ,not only provide the side view with turn signal activation, but will also provide a side view anytime the angle between the TV and the Trailer exceeds approx. 25 degrees, turn signal or not (really great when your backing into a drive with tight curbs ) . A bonus, perhaps , is the red zone alert overlaid on the side view when an overtaking vehicle is along side the trailer.
