- Split Screen Display: The 10-inch monitor can display feeds from up to four cameras simultaneously or individually, eliminating blind spots. Use the 'MODE' button on the monitor or remote control to cycle through display modes.
- Parking Guidelines: The system features adjustable parking guidelines to assist in judging distances to objects. These guidelines can be turned ON or OFF via the monitor settings.
